Qualitative Methods
Why would we use them?
What are they like?
How do we assure validity?
Some elaboration on Table 13.1
Quantitative Research
• Emphasis on prediction and regular patterns
• Testing hypotheses with an eye to falsification
• When random sampling is used, generalizable results are obtained
• Report: Statistical in nature, with significance tests and graphs
Qualitative Research
• Emphasis on understanding patterns within contexts
• Generating and verifying hypothesized explanations
• Results are generalized by approximation to the traits of the participants studied
• Report: Rich narrative with direct quotations. May also have graphs or counts.

Think and Talk – Qualitative Possibilities in Quantitative Studies
• Milgram’s obedience studies• The design of survey questions
(do they capture the full richness of the answer?)
• The language acquisition studies (Chinese and American language)
• The Hole in the Wall Studies• The Change-Blindness study

Table 13.3 – Code the indicators
• Descriptive validity– Investigator triangulation
• Interpretive validity– Participant feedback– Low-inference descriptors (define “low inference”)
• Theoretical validity– Extended fieldwork– Theory triangulation– Pattern matching– Peer review
Table 13.3 – Code the indicators
• Internal validity(compare with experimental designs)– (Explain ideographic vs nomological causation)– Researcher-as-detective– Methods triangulation– Data triangulation
• External validity (compare with experimental designs)– Naturalistic generalization– Theoretical generalization
