Purpose Of Mixed Method Research

Purpose Of Mixed Method Research

Research objectives the mixed method contains the overall research objectives, information on quantitative and qualitative research elements, and reasons/rationalizations to mix the two elements to examine the research problem. The purpose of mixed method research is usually indicated first, in the introduction, to provide an initial guide for the reader in understanding the quantitative and qualitative parts of research within it. In the following, I present some instructions on how to structure and present the research objectives of the mixed method.

  1. Start by writing words that clearly indicate the purpose of the research to be described, such as “purpose.....“or " means....”
  2. Explain the purpose of the study from a content perspective, such as “the goal is to study organizational effectiveness” or “the goal is to observe stepchild families” to understand the overall intent of the study first before the researcher divides his research into quantitative and qualitative sections.
  3. Indicate the type of mixed method design used, whether it is sequential, concurrent, or transformational.
  4. Explain the rationale/rationalization combined with quantitative and qualitative data. These reasons can be any of the following (see Chapter 10 for more details):

  • To better understand the research problem by converging (or triangulating) quantitative data in the form of numbers and qualitative data in the form of descriptive details.
  • To explore the views of participants (qualitative) to then be analyzed based on a broad sample (quantitative).
  • To obtain quantitative statistical results from a sample, then follow up by interviewing or observing a number of individuals to help further explain the statistical results that have been obtained (SEE ALSO O'cathain, Murphy & Nicholl, 2007).
  • To uncover the tendencies and rights of oppressed groups or individuals.
  1. Apply the characteristics of good qualitative research objectives, such as focusing on one main phenomenon, using action words and indirect language, mentioning the research strategy, and describing the participants and location of the study.
  2. Also apply the characteristics of good quantitative research objectives, such as mentioning a theory and variables, linking variables or comparing groups of variables, arranging these variables starting from free variables first and then bound variables, mentioning research strategies, and detailing participants and research sites.
  3. Consider additional information about the types/strategies of qualitative and quantitative data collection.

Based on the above elements, the following are presented four examples of mixed method research objectives (Creswell & Plano Clark, 2007). The first two examples are sequential research with one data collection strategy that also builds another data collection strategy. The third example is concurrent research by applying two data collection strategies at one time and then brought together in data analysis. 

The fourth example is the research of the transformative mixture method which is based on concurrent design.

1. Sequential research with quantitative stage in the second order which is based on the qualitative stage in the first order:

The purpose of this two-stage sequential mixed method research is to.... (indicate the purpose of the study by content). The first stage is a qualitative exploration of ...(main phenomenon) by collecting(types of data) from(participants) in (research location). The findings of this qualitative stage are then used to test(a theory, problem formulation, or hypothesis)which (linking? compare?) (independent variable) with(dependent variable) against(sample from the population) in(research location). The reasons for the precedence of qualitative data collection are due(e.g., the instruments are unsuitable or unavailable, the variable variables are unknown, and there is little theory or taxonomy that can serve as a rigorous ' guide).

2. Sequential research with qualitative stages of follow-up (in the second order) that helped explain the previous quantitative stage (in the first order):

The purpose of this two-stage sequential mixed method research is to (specify research objectives by content). In the first stage, the formulation of a quantitative research problem or hypothesis will explain the relationship or comparison of (independent variables) and(dependent variables) by involving(research participants) in (research location). 

The information from the first stage will be further explored in the second stage, the qualitative stage. In this second stage, qualitative interviews or observations are used to re-examine (quantitative results) by exploring aspects (main phenomena) by involving(participants) in(research location). The reason these quantitative methods are followed up with qualitative methods is to (i.e., better understand and explain previously obtained quantitative results).

3. Concurrent research by collecting quantitative data and qualitative data at the same time, then combining the two to be able to understand the research problem better : 

The purpose of this concurrent mixture Method Research is to..:.. (indicate the purpose of the study by content). In this study,.... (quantitative instrument) will be used to measure the relationship between (independent variable) and (dependent variable). At the same time, (the main phenomena) will be explored using (qualitative interviews or observations) with (the participants) at (the research site). The origin of combining quantitative data and qualitative data is to better understand the research problem by verging on qualitative data (in the form of numbers) and quantitative data (in the form of descriptive views).

4. The last example is the research of mixed methods with transform palliative strategies. This example is written based on concurrent research, but the name of the mixed method project may use concurrent strategies (quantitative data and qualitative data collected at the same time) or sequential strategies (two types of data collected in stages). 

It is said to be a transformative strategy because the purpose of this study is to address the main issues related to marginalized groups or individuals. In addition, the results of this kind of research usually advocate for the needs of the group or individual so that the purpose of the research is accompanied by an explanation of the efforts/expectations of transformation (change) in the research objectives. The purpose of this concurrent mixed-method research is to (mention the issues that need to be discussed related to marginalized groups or individuals). 

In this study,..... (quantitative instruments) will be used to measure the relationship between (independent variables) and(dependent variables). At the same time, (the main phenomenon) will be explored also by using (interviews or qualitative observations)with/against (the participants) in (the research site). The reason quantitative data and qualitative data are combined is to better understand the research problem by converging quantitative data (in the form of numbers) and qualitative data (in the form of detailed views), and to advocate for change/transformation for (groups or individuals).
