Chapter 20: Data Analysis in Qualitative and Mixed Research
Answers to Review Questions
20.1. What is interim analysis?
Interim analysis is the cyclical process of collecting and analyzing data during a single research study.
20.2. What is memoing?
Memoing is the recording of reflective notes about what you are learning from the data.
20.3. What are visual data, and how might they be analyzed?
Visual data are images or data that we sense with our eyes (e.g., photographs, art, pictures, video images, nonverbal expressions). They are analyzed using one or a combination of the following three techniques:
• Photo interviewing analysis—analysis is done only by the participant who examines and “analyzes” visual images.
• Semiotic visual analysis—the identification and interpretation, during analysis, of the symbolic meaning of visual data.
• Visual content analysis—the identification and counting of events, characteristics, or other phenomena in visual data.
20.4. Why is it important to transcribe qualitative data when possible?
So that you can import the text file into a qualitative data analysis software program to facilitate data analysis. Another reason is so that you can analyze the data line-by-line.
20.5. What is the difference between segmenting and coding?
Segmenting is the process of dividing data into meaningful analytical units; coding is the process of marking segments of data with symbols, descriptive words, or category names.
20.6. What is the difference between inductive and a priori codes?
Inductive codes are generated by a researcher by directly examining the data; a priori codes are developed before examining the current data.
20.7. What is the difference between co-occurring and facesheet codes?
Co-occurring codes are codes that partially or completely overlap; facesheet codes are codes that apply to a complete document or case.
20.8. Explain the process of enumeration.
Enumeration is the process of quantifying data (frequencies, percentages, cross-tabulations).
• For example, you may count the number of times that a particular word occurs or you may count the number of times a category appears in your data.
20.9. What is a hierarchical category system, and why can it be useful to construct hierarchical systems?
A hierarchical category system not only includes categories, it also puts categories into subsets. A hierarchy by definition includes more than one level. Hence, a hierarchical category system includes categories taken to be at more than one level. Creating a hierarchical category system can be a very effective way to make sense of your data. You can see an example in Figure 20.2.
20.10. How do qualitative researchers show relationships among categories?
One way is to create a hierarchical category system which is an example of the strict inclusion form of relationship. Many other types of relationships are given in Table 20.6: spatial, cause-effect, rationale, location for action, function, means-end, sequence, and attribution. The key is to not just to come up with an unordered list of categories, but, instead, to determine how the categories can be related to one another to find patterns in the data and to help make sense of the data. In Figure 20.3, we showed how you can come up with new categories by crossing two dimensions of categories; in Table 20.7, we showed some categories organized by time or sequence.
20.11. How are network diagrams used in qualitative research?
A network diagram is yet another way to organize categories. It is done pictorially. These diagrams can be used in both qualitative and quantitative research. These diagrams are especially helpful for showing hypothesized causal relations or relations that occur over time. One example of a network diagram is shown in Figure 20.4.
20.12. What are the five types of validity that are of potential importance in qualitative research, and what are their definitions?
1. Descriptive validity—the factual accuracy of an account as reported by the researcher.
2. Interpretive validity—accurately portraying the meaning given by the participants to what is being studied.
3. Theoretical validity—the degree to which a theoretical explanation fits the data.
4. Internal validity—causal validity (idiographic causation is especially important in qualitative research, but some evidence of nomothetic causation can also be obtained in qualitative research; qualitative research is especially helpful to explicating causal explanation).
5. External validity—generalizing validity.
20.13. What are the 13 strategies that are used to promote validity in qualitative research, and what are their definitions?
They are shown in the following table from the earlier chapter that discussed the validity of research results (i.e., Chapter 11):

20.14. What are some of the capabilities of computer programs for data analysis?
Segmenting, coding, enumeration, drawing of network diagrams, drawing hierarchical category diagrams, doing advanced searches using Boolean operators, searching for various kinds of relationships in the data (such as Spradley’s relationships shown in Table 20.6), integrating data from multiple files (e.g., different interviews, field notes, memos, etc.), etc.
20.15. What are some of the leading qualitative data analysis computer programs?
The most popular programs are: MAXQDA, hyperRESEARCH, QDA Miner, and NVivo. Other software packages include Ethnograph, Dedoose, and atlas.
20.16. What are the four types of analysis corresponding to the four cells in the mixed research data analysis matrix?
(1) Monodata-monoanalysis.
(2) Monodata-multianalysis.
(3) Multidata-monoanalysis.
(4) Multidata-multianalysis.
20.17. What are some of the different strategies or procedures that are used in mixed data analysis?
First, as a starting point, data typically are analyzed using the standard techniques (i.e., quantitative analysis of quantitative data and qualitative analysis of qualitative data). Second, many additional strategies are used, such as quantitizing, qualitizing, and merging data into a single data set and doing integrated analyses. The area of data analysis in mixed research is a rapidly growing area of development.
