Mixed Methods Research Design is a type of research design where the researcher employs both _____and ______ research methods to collect and analyze data, and report research findings in a ____ or _____ study
quantitative and qualitative
single or multiphase
4 types of Quantitative Approaches
4 Qualitiative Approaches
Simply collecting quantitative and qualitative data and reporting results is not mixed methods research---data must be what?
integrated through merging or connecting the data
Mixed methods designs have emerged, but not without controversy about what 2 things?
paradigm-method fit and best paradigm
What is the use of multiple methods to ensure that the data collected is trustworthy and accurate?
The essence of mixed methods research are to?
Enrich the findings
Increase depth and breadth
Testing a theory or model
Seeking participants for input
With mixed methods research, your research questions must address both what?
the quantitative and qualitative aspects of your study
What determines the priority of qualitative or quantitative methods?
The order of the questions
hypotheses written in literary form represents?
variables in the abstract
hypotheses written in operational form represents?
specific information about variables in study
Null Hypothesis is?
a written statement that predicts that there is no difference or no relationship, between groups related to a particular variable
What are the type of studies where the use of quantitative and qualitative methods is predetermined and planned at the start of the research process, and the procedures are implemented as planned?
What type of studies happen when the use of mixed methods arises due to issues that develop during the process of conducting the research
When do emergent studies generally occur?
when second approach is added after the study begins because one method is found to be inadequate
When using a _____ approach both qualitative and quantitative questions can be identified as one set of questions does not rely on the other.
In a ____ approach, the second part of the approach elaborates on the first.
4 Considerations for a Mixed method design?
1.Determine the order in which you will implement the qualitative and quantitative aspects of your study.
2.Determine the weight that will be given to the quantitative and qualitative data.
3.Determine how the two types of data will be mixed/combined.
4.Determine the theory that will guide your design.
4 types of mixed method designs
Embedded or Nested Design
______ is the most challenging of the four types of mixed methods designs because of the amount of researcher effort necessary.
3 weaknesses of triangulation design
-amount of researcher effort necessary.
-Large amount of time needed to implement design because you muse concurrently gather qualitative and quantitative data.
-Differing findings between qualitative and quantitative research may require additional research and data collection to clarify disparities.
3 strengths of triangulation design
-Ideal design for research teams as the data collection can be divided.
-Efficient in that both types of research are collected concurrently
-Combines the weaknesses of one type of data (quantitative), with the strengths of another type (qualitative).
What design is used when researchers need to answer questions from a different perspective and their research has primarily focused on one type of data?
What type of design is particularly useful when the researcher seeks to insert a qualitative component within a quantitative design?
Embedded design (think of one type of data is the lead role in the movie and other type of data is the supporting actor)
Can quantitative components be embedded in a qualitative design?
Yes but this rarely occurs.
Weaknesses of Embedded/nested Design?
Difficult to integrate the results when two methods are used to answer different research questions.
Very few examples exist of integrating quantitative data with qualitative data.
3 strengths of the embedded design?
-Provides you with an opportunity to follow-up on early results.
-You focus on one type of design, reducing your research time and effort.
-More manageable because one method requires less data than another.
What is a two-phase mixed methods design in which qualitative data helps explain initial quantitative results?
What design can be ideal for researchers who are looking for additional qualitative data to explain quantitative results?
What design is begun by collecting quantitative data and then collencting qualitative data to assist in explaining the quantative results?
3 stregnths of explanatory design
-Easy for the reader to understand and identify. Each part of the process (i.e. the quantitative and then the qualitative) is highlighted in the research.
-You do not have to integrate two types of data.
-Methods conducted separately, research team is unnecessary.
4 weaknesses of explanatory design
-Requires you to have skills in quantitative and qualitative data collection.
-Sometimes difficult to determine aspects of the study for qualitative follow-up.
-As a researcher, you must determine if study participants should be used in both phases of the research or to go back to the original population and obtain a new sample for the qualitative portion of the study.
-Institutional Review Board approval can be difficult to obtain because you cannot identify the number of qualitative participants needed until the quantitative portion of the study has been conducted
What design is a two-phase design where qualitative results are obtained first followed by the quantitative in order to inform the qualitative data?
What design is used when there are no measurements or instruments available to guide the study, when the variables are unknown, and the study has no guiding framework or theory in use?
2 strengths of exploratory design
Design is easily applied to multiphase and single studies.
Emphasizes qualitative component, includes quantitative component as additional strength to the study.
2 weakness of exploratory design
Requires more time to implement, you need to take this into consideration (especially for a thesis or dissertation).
Difficult to specify procedures of quantitative phase when applying for internal review board approval.
Triangulation is a one or two phase design?
One phase design- meaning researcher will implement the quantitiative and qualitative aspects of the study concurrently (both types carry equal weight)
What is purposeful sampling?
thost that you specficially choose and that contain a certainelement that will highlight and inform a particular aspect of teh study (sample is not randomand may subject to researcher bias)
What is the ideal sample size?
it depends; finding the ideal sample size depends of the method of data collection in use.
When considering quantitative sampling, what do you have to keep in mind?
-Method of data collection-some methods are expensive (interview), some cheap (questionaries)
-Degree of precision desired in final results- sufficient sample to assure groups are repersented in large enough numbers to make findings accurate.
What is sampling error?
the larger the difference between sample size and population, bigger sampling error (in terms of the sample being an accurate representation of the entire population)
One warning in qualtitative research sampling?
the larger the number of participants, the less depth and detail that can go into data collection with each
A mediating or intervening variable is one that?
mediate the effect of the independent variable on the dependent variable
(descriptive questions are wrtieen for each independent and dependent variable and any significant mediating variables in study)
Two types of questions that can be created in quantitive research?
descriptive and multivariate questions
Descriptive questions are followed by multivariate questions that do what?
compare or relate variables
