Unit 2: Research Methods
Study in depth -> reveal universal principles
Observe & record bhv in naturally occurring situations
Correlation & Experiments
How well 2 variables change w/ each other?
How well both predict each other?
Experimental & Control grp
Measure & describe grp's characteristics
Can we generalize the result to the pop?
sample averages are reliable
Diff b/w them is large
How likely it is the result occurred by chance?
Do not determine the result's
When we will generalize? (reliability)
Low-variability -> more reliable avg
more cases > fewer cases
To create theoretical principles -> help explain everyday bhvs
Minimally predict and individual's bhv
The underlying processes are the same under varied cultures & gender
