However, despite these ongoing quarrels between your methodological practices of qualitative and quantitative research (Gage, 1989); blended methods represent an easy developing field of interpersonal science methodology. As all methods have specific margins and particular talents, many discussants suggest that qualitative and quantitative methods should be mixed in order to compensate for their common weaknesses (Tashakkori & Teddlie, 2003). Moreover, it is claimed that this movement scripts the start of a new era in public research indicated by way of a tendency to incorporate quantitative and qualitative methods pragmatically unencumbered by old debates (Johnson & Turner, 2003). Therefore it is emphasized that the uses of your mixed-method design has an important tool in overcoming the constraints of both qualitative and quantitative mono-method research.
This essay deals with social ideas that influence qualitative and qualitative research methods employed in interpersonal sciences as either in concept separable or even as irreconcilable methods of communal sciences. It starts off with a characterization of positivism, Interpretivism and realism; and links these ideas to the foundation of qualitative and quantitative research methods. Then, it shows how they deal with the various areas of the qualitative-quantitative split. Finally, it is the intention to show how the mixed methodological procedure may be integrated in a coherent way to add value and help out with the design of a single research project. With an focus on the variations and similarities between quantitative and qualitative methods providing the foundation for exploring the methods of merging both approaches to triumph over their weaknesses by giving a commentary of the complementary strengths of each tradition.
Characterizing Positivism, Interpretivism and Realism approaches
Few sociologists would illustrate themselves as a positivist, interpretivist or realist. They are terms used mainly by methodologists and social theorists to describe and evaluate the theoretical assumptions underlying different approaches to research (Bickhard, 1992; Johnson, 2006; Hibberd, 2010). There are many different views in sociology in what societies are and the best ways of obtaining understanding of them. This part of the essay simplifies concerns to some extent by characterizing three of the very most influential theories of knowledge in sociology: positivism, interpretivism and realism (Bryman, 1998 and 2001; Hibberd 2010).
Positivism
Positivism is frequently used to stand for the epistemological assumption that empirical knowledge predicated on key points of objectivity, verificationism, and reproducibility is the building blocks of all traditional knowledge (Bryman, 2001; Hanzel, 2010). The word positivist has been crucial for a while in the real human sciences because positivist tends to subscribe to a number of ideas that have room in present-day science and viewpoint (Hanzel, 2010). Positivism views that sociology can and should use the techniques of the natural sciences, that not usually mean using tests because there are all sorts of honest issues with doing that, but positivists do believe that sociologists should use quantitative methods and aim to identify and assess social structures. Being a philosophical methodology, positivism encompasses a group of notions. Desk 1 below, provides main characters for positivist key ideas. It implies that positivists summarize every item by being against metaphysics (Hacking, 1983).
Character
Description
emphasis upon verification
Significant propositions are those whose fact or falsehood can be resolved for some reason.
Pro-observation
What we can easily see, feel, touch, and the like supply the best content or base for all the break of our non mathematical knowledge.
Discoverability
Scientific knowledge is something uncovered (somewhat than produced or constructed).
Anti-cause
There is no causality in dynamics, in addition to the constancy with which occurrences of 1 kind are accompanied by events of another kind.
Downplaying explanation
Explanation can help plan phenomena, but do not provide any deeper answer to Why questions except to say that the phenomena regularly occur in such and such a way.
Anti-theoretical entities
Positivists have a tendency to be non-realists, not only because they restrict fact to the observable but also because they are against triggers and are dubious about explanations.

Positivist theory argues that the techniques of the natural sciences are applicable to the analysis of societies. Inside the positivist view, sociology includes the search for causal interactions between observable phenomena and ideas are examined against observations (Hibberd, 2009). Researchers adopting a positivist point of view may still be interested in learning about people's subjective views. For example, they explore things such as behaviour and views through survey research (Michell, 2003). However, they start to see the activity of sociology as describing why people behave in the manner they do, and exactly how people sense about things cannot be explained scientifically.
Interpretivist
Interpretivists do not necessarily reject the positivist consideration of knowledge, however they question the idea that the logic and methods of natural technology can be imported into the study of societies. Utmost Weber was one of the key influences on the interpretivist traditions in sociology. For him, 'natural knowledge' and 'communal technology' are two very different enterprises requiring a different logic and various methods (Bryman, 1982).
At the heart of interpretivist critique of positivism is a humanist point of view. Some of those favouring an interpretivist view of sociology have long argued that in their visit a scientific description of sociable life, positivist have sometimes overlooked they are studying people, and also to study people you will need to get away and explore that they think and react in everyday situations. Interpretivists claim that unlike objects in nature, human beings can transform their behaviour if they know they are really being noticed (Collins, 1984; Guba, 1987). So, interpretivists argue that if we want to understand social action, we need to check out the reasons and meanings which that action has for people (Marsh, 2002). Take the example of criminal offense, a positivist would dispute that researchers can simply measure offense using quantitative methods and identify habits and correlations. While, an interpretivist would claim that we need to understand what people imply by crime, how they come to categorize certain activities as 'legal' and then research who comes to be observed as criminal in a specific society. The purpose of interpretivist strategies in sociology is to understand the subjective experience of those being studied, the way they think and feel and how they action in their natural contexts (Marsh, 2002; Johnson, 2006).
Therefore, although interpretivists still make an effort to be objective and organized in their research, the main element criterion in interpretivist epistemology is validity. The favoured research design is ethnography and the primary methods are ones that help analysts understand cultural life from the idea of view of those being examined, such as unstructured observation, unstructured interviews and personal documents. Interpretivism has provided a powerful critique of several of the taken-for-granted ideas of positivism that are trusted in sociology and in other communal sciences (Marsh, 2002). It has additionally influenced a complete field of research illuminating people's everyday routine activities. However, interpretivists' accounts are criticised by some sociologists for not providing testable hypotheses that may be evaluated. This may lead to relativism where one theory, or research, is seen as just as good as other.
Realism
Realist theory, like positivism, retains that sociology can, and should, follow the reasoning and ways of the natural sciences, on the other hand, it differs from positivism in its interpretation of knowledge (Hartwig, 2007; Hibberd, 2010). In positivist research, ideas are examined against observations and found to be 'true' or 'fake' or someplace in between. In simple terms, the 'facts' are the judge of the idea (Hibberd, 2010). Realists do not get this to clear-cut parting because they don't assume that 'observations' can be segregated from 'theories' (Parker, 2003; Hartwig, 2007). They dispute that no form of knowledge relies exclusively on observable empirical evidence. There are always areas of any form of fact that remain concealed under the surface of what can be viewed (Duran, 2005; Hibberd, 2010). According to realists, the aim of methodical work is to discover the root causal mechanisms that result in observable regularities.
Realists see research being guided mainly by 'scientific' criteria, such as the systematic collection of evidence, trustworthiness and transparency. However, because they recognise the value of the subjective dimensions of human action, they also include methods that doc the validity of people's activities (Bhaskar, 1999). Research designs are more likely to be experimental or comparative in realist research, but there is no particular determination to either quantitative or qualitative methods (Parker, 2003; Hartwig 2007). The focus of realist strategy, however, is on theory. Realists argue that as there is absolutely no such thing as theory-free data: sociological methods should be specifically focused on the evaluation and assessment of theoretical concepts, explanations and insurance policies.
The development of a clear, realist epistemology is relatively recent in sociology and owes much to 'new realist' freelance writers like Bhaskar (1986, 1999) and Pawson (1989). They have provided another type of interpretation of research and its relationship to social sciences, and a expanding alternative to the dominant theories of positivism and Interpretivism that laid the foundations for a non-empiricist epistemology in public technology (Hibberd, 2009 and 2010). However, they might say that doesn't mean that either group of methods, positivist or interpretive, have to be ditched. The realist's argument is the fact sociologists can be pragmatic and use whatever methods are appropriate for particular circumstances. Friendly reality is complex and to examine it, sociologists can draw on both positivist and interpretivist methods.
For purists, the assumptions associated with quantitative and qualitative paradigms regarding how the world is viewed and what it's important to learn are irreconcilable. They envisage that both methods stem from different metaphysical and epistemological assumptions about the nature of research (Bryman, 1984; Collins, 1984; Tashakkori & Teddlie, 1998). Purists advocate that the techniques and tenets from positivism and post-positivism cannot and really should not be blended (Smith, 1983). They think that the axioms of post-positivism and positivism have mutually exclusive assumptions about world; therefore, the research methods derived under each are believed to be mutually exclusive as well
In agreement with purists and approval of both positivist and post positivist paradigms, situationalists maintain that qualitative and quantitative methods are complementary but shouldn't be integrated in a single research. However, they believe definite research questions associate more to quantitative solutions, whereas other research questions tend to be more suited to qualitative methods (Onwuegbuzie and Leech, 2005). Thus, although representing completely different directions, the two approaches are cured as being complementary.
By contrast, pragmatists, unlike purists and situationalists, contend that a false separation is out there between quantitative and qualitative approaches (Newman & Benz, 1998). They advocate the integration of methods within a single research. Sieber (1973) articulated that because both approaches have intrinsic advantages and weaknesses, researchers should utilize the strengths of both techniques to be able to comprehend better communal phenomena. Indeed, pragmatists assign to the school of thought that the research question should drive the methods used (Onwuegbuzie and Leech, 2005). Regardless, experts who ascribe to epistemological purity disregard the idea that research methodologies are simply just tools that can aid our knowledge of the planet.
It can be done to argue that we now have overwhelmingly more similarities between quantitative and qualitative approaches than there are variations (Onwuegbuzie and Leech, 2005). Bothe and Andreatta (2004), add that both methods involve the use of observations to address research questions, illustrate their data, construct descriptive arguments of their data, and speculate about why the results they observed occurred as they performed. Both models of researchers choose and use analytical techniques that can obtain the maximal meaning from other data, therefore that results have utility with regards to their respected views of simple fact (Kelle, 2006).
Both methods investigators utilize ways to validate their data. Such techniques include prolonged observation with ongoing and prolonged inspection of the research study with concern to rival explanations. Replication of the chosen research method to other cases (of which can include extreme scenarios) supplies the opportunity to gain validity of results and the methodological procedure used, by means of a representative review group to permit for reliable generalisations to be produced. Triangulation, confirmation of researcher results and weighting of the data identifies and resolves researcher bias and 'thick explanation' (Creswell, 1998, cited Onwuegbuzie and Leech, 2005) which may effect on the studies. Debriefing of analysis individuals may obtain valuable responses from participants also.
Moreover, quantitative and qualitative studies stand for an interactive range and the role of theory is central for both paradigms. Specifically, in qualitative research the most common purposes are those of theory initiation and theory building, whereas in quantitative research the most frequent goals are those of theory screening and theory changes (Newman & Benz, 1998). Evidently, neither tradition is independent of the other, nor can either school encompass the whole research process. Thus, both quantitative and qualitative research techniques are needed to gain a far more complete knowledge of phenomena (Newman & Benz, 1998).
Hence, there are numerous parallels can be found between quantitative and qualitative research. Indeed, the purity of a study paradigm is a function of the extent to which the researcher is ready to comply with its main assumptions (Luttrell, Wendy, 2005). This suggests that methodological 'pluralism' (Larsson, 2009) should be advertised, the simplest way for this to occur is for as much investigators as you possibly can to be 'pragmatic' analysts (Onwuegbuzie and Leech, 2005).
Combined research methods and function in the research process
A mixture of qualitative and quantitative research strategies can assist in practical answers to overcome limitations of mono-method research mentioned for the last 50 years (Kelle, 2006). However, it is hardly ever addressed in current debates whether it's possible to build up solid methodological approaches for structuring research methods based on that insight of combining qualitative and quantitative methods (Creswell et al. , 2003; Tashakkori & Teddlie, 2003; Onwuegbuzie & Leech, 2005), though there is a broad agreement a use of multiple methods with complementary talents and various weaknesses can add value to an individual research. Despite this, the dialogue provides only sparse information about which designs could beat which weaknesses of mono-method research. Furthermore, there continues to be a lack of agreement about the precise classification and terminology of different mixed methods, 'combined method' or 'multi-method designs' which are used in research practice (Tashakkori & Teddlie, 2003, cited Onwuegbuzie & Leech, 2005, p:307 ).
By starting the study process with a qualitative research, researchers may obtain access to knowledge that helps them to build up the correct theoretical concepts and also to construct constant research instruments later on that cover relevant phenomena by consequential and relevant items. Such a design helps to overcome 'the limited transferability of findings from qualitative research as well as the primarily mentioned hazards of the heuristics of commonsense knowledge' (Onwuegbuzie and Leech, 2005, p: 307). This process can help construct consistent research devices that cover relevant phenomena by consequential and relevant substances.
Meanwhile, incorporating qualitative and quantitative methods the contrary way could be useful oftentimes; that means you start with a quantitative review, accompanied by qualitative questions (Onwuegbuzie and Leech, 2005; Lund 2005). In such a quantitative-qualitative approach, problem areas and research questions are discovered by following a quantitative study that will need to be further investigated by using qualitative data and methods. The issue of quantitative research tackled by this design is usually the difficulty to understand statistical studies without additional socio ethnical knowledge.
Furthermore, the quantitative part of the sequential quantitative-qualitative design can guide organized case comparison in the next qualitative inquiry by assisting to identify conditions for the selection of cases and by giving a sampling frame (Onwuegbuzie and Leech, 2005; Kelle, 2006). Thus, this design can help defeat an important risk of validity existing in qualitative research that experts focus on distant and marginal cases. Another problem of qualitative research can be resolved by this design: it can help to avoid a qualitative research with an outsized scope that covers a domains too extensive to be captured with the help of a little qualitative sample. Onwuegbuzie and Leech (2005) provide a simple example to understand these problem: a qualitative study of family life in a modern day city would need to take into account a lot more different kinds of families when compared to a similar analysis in a normal rural community in the first decades of the twentieth century. By drawing on statistical materials about the distribution of different family forms, the lowest requirements for qualitative sampling could be easily captured, and could be well advised to downsize the study question and research website (Bryman, 2001; Onwuegbuzie and Leech, 2005).
On the other hand, a parallel qualitative-quantitative design can fulfil similar functions to a sequential design: the qualitative part of the study can offer information that really helps to understand statistical relationships, to build up explanations also to identify additional variables that increase variance already discussed in the quantitative data. A great benefit for a parallel qualitative-quantitative design is the fact that it helps to identify dimension problems and methodological artefact of both qualitative and quantitative data, as the same persons are interviewed with different techniques (Bryman, 1992 and 2001). However, this parallel design methodology encloses an important drawback, it is the fact that qualitative sampling and data collection can't be systematically developed from research questions derived from quantitative data; so that it can easily be the truth that the available qualitative data provide no answers for questions coming from the quantitative review, as these were not collected for that purpose.
Conclusion
It is shown throughout this article that the theoretical methodology influences the methodological approach and vice versa. Many studies in sociology use a combination of positivist, interpretivist and, realist ideas. The article shows that the impact of positivism has influenced much of social research most widespread research methods. A few of these include research, questionnaires and statistical models. Analysts applying a positivist methodology for their study consider large-scale test surveys and handled laboratory experiments as suitable research methods. These methods can be justified as they allow positivist analysts to employ empirical and logical quantitative data. While, interpretivism utilizes qualitative solutions to understand people, not to measure them, it endeavors to capture truth in conversation, however, will not necessarily exclude quantitative methods. Whereas, quantitative results from a positivist method just like a survey are improbable to provide understanding of this deeper certainty and therefore shouldn't be a significant part of any realism research study, in essence, because realism research data are nearly always qualitative data about meanings.
The article provides several advantages of performing combined method research. Experts of social science use a multitude of research methods to gain and improve knowledge and theory. The different types of research methodologies, quantitative and qualitative, are associated with the epistemological and theoretical perspectives the researcher wishes to adopt. The essay confirmed that quantitative and qualitative methods can fulfil different, yet, complementary purposes within mixed-method designs. Quantitative methods can provide a synopsis about the website under review and can illustrate its heterogeneity over a macro-level, whereas qualitative methods can be used to access local understanding of the field in order to build up theoretical principles and explanations that cover phenomena relevant for the study site. Thus, quantitative and qualitative methods cannot replace one another, but help illuminate different aspects of sociological phenomena: in a sociological investigation quantitative methods can summarize the actions of many different actors, whereas qualitative methods provide information about possible reasons for these actions. In such instances qualitative and quantitative methods help to answer different questions like the kinds of activities social celebrities typically perform.
Finally, the essay exhibited that results from qualitative interviews can help identify unobserved heterogeneity in quantitative data as well as the previously unknown explaining variables and unspecified models (Kelle, 2006). Additionally it is clear that results from the qualitative part of mixed-methods design can help understand what once incomprehensible statistical studies were; the qualitative part of the research can help to discover a lack of validity of quantitative dimension operations and devices. Additionally, in a sequential quantitative-qualitative design quantitative research can help to guide the selection of instances in qualitative small studies. In this case the quantitative part of the study can help confirm findings from a qualitative research and to copy these results to other domains.
