Problem Statement
What is your problem statement?

Purpose
• Determine the causes• Build a workable curriculum program• Provide students with test taking techniques• Improve student scores

Background Description
• Population
• Work Setting
• Writer’s Role
Qualitative Data Analysis Techniques
•Qualitative data are analyzed inductively
•Specific observations look for patterns develop
hypotheses develop general conclusions
–Potentially overwhelming task
–Goal is to reduce volume of information collected
–Risk minimizing, simplifying, distorting data
•Must rely on a coding scheme—system for grouping data
into categories of similar information
–Highly individualized type of system

Qualitative Data Analysis Techniques
•Often necessitates reading, rereading, rereading again
your data
•Must get to “know” your qualitative data very well
•Steps in the process:–Reduce amount of narrative data through use of coding
scheme
–Describe main characteristics of categories (connect data to
research questions)
–Interpret what has been simplified and organized
http://studysites.sagepub.com/mertler4e/study/chapter.htm
Qualitative Data Analysis Techniques
•Also, engage in introspection
–Reflective practice that helps to ensure that you
remain objective and “emotionally unattached” to data
•Assistance with analysis through software
–Analysis of qualitative data cannot be “done” on the
computer (due to inductive nature)
–Software can help store and organize data
http://studysites.sagepub.com/mertler4e/study/chapter.htm
Quantitative Data Analysis Techniques
•Quantitative data are analyzed deductively
•Identify topic focus with research questions or
hypotheses collect and analyze data develop
conclusions
•Can use either descriptive or inferential statistics
–Descriptive statistics—procedures that simplify, summarize,
and organize numerical data
–Inferential statistics—procedures used to determine how likely
given statistical results are for an entire population based on a
sample
http://studysites.sagepub.com/mertler4e/study/chapter.htm
Quantitative Data Analysis Techniques
•Descriptive statistics–Measures of central tendency—single value to
indicate what is typical or standard about a group of
individuals
•Mean
•Median
•Mode
–Measure of dispersion—single value to indicate how
scores are different, or what is atypical
•Range
•Standard deviation
http://studysites.sagepub.com/mertler4e/study/chapter.htm
Quantitative Data Analysis Techniques
•Descriptive statistics (cont’d.)
–Measures of relationship—statistical measure of strength
of association between variables
•Correlation coefficients
http://studysites.sagepub.com/mertler4e/study/chapter.htm
Quantitative Data Analysis Techniques
•Descriptive statistics (cont’d.)
–Visual displays of data—not really a statistical
procedure; simply ways to “show” data
•Frequency distribution table
•Histograms
•Bar charts
•Pie charts
http://studysites.sagepub.com/mertler4e/study/chapter.htm
Quantitative Data Analysis Techniques
•Statistical software
–Numerous software packages exist; some are very
costly
–Very effective, Web-based alternative: StatCrunch
(www.statcrunch.com)

Action research checklistAnalyzing Data in Action Research
☐Revisit your research question(s) and your previous decisions about the use of qualitative, quantitative, or mixed-methods data for your action research.
☐Develop a plan for analyzing your data (see below).☐If you have collected qualitative data, decide how you plan to analyze your data:
☐Will you code, organize, and analyze your data by hand?☐How will you actually do this (notecards, sticky notes, etc.)?
☐Will you use some sort of software (see the “Related Websites” section of this chapter) to code, organize, and analyze your data?
☐If you have collected quantitative data, decide how you plan to analyze your data:☐Be sure to specify the type of analysis—descriptive (e.g., frequencies, mean, median, graphs,
etc.) or inferential statistics (e.g., t-test, ANOVA, chi-square test, etc.)—you plan to use.☐Will you analyze your data by hand, perhaps using only a calculator?
☐Will you use some sort of software (e.g., StatCrunch, or others in the “Related Websites” section of this chapter) to analyze your data?
☐Anticipate how you will present the results of your data analysis:☐Will you present all of your results in narrative form?
☐Will you utilize any tables, graphs, etc?.☐Develop a timeline for your data analyses.
