Question | Answer |
---|---|
Goals of Beh Research | Description/Predicting/Explaining/Controlling |
Scientific Approach Requires | Systematic Empiricism/ Public Verification/ Testability |
Measurement | operational definitions |
Theory | educated guess |
a good theory | parsimonious/ falsifiable |
proof | logical impossibility |
disproof | practical impossibility |
Descriptive research | answers "what"- polls |
correlational research | relationship? |
experimental research | causes (IV and DV) |
quasi-experimental | can't manipulate IV |
inferential statistics | did something happen by chance? |
variance | amount but not type/ sum(x-Xbar)/n-1 |
error variance | factors not being investigated |
Cohen's small | .01 |
Cohen's medium | .06 |
Cohen's large | >.15 |
behavioral measures | what subjects do |
nominal | naming/no order |
ordinal | order |
interval | relative distance btw ratings |
ratio | divide & multiply quantities |
most stats measures require at least | interval measures |
reliability | consistency |
test-retest reliability | same individual test many times= variability btw scores= error variance |
interitem relaibility | randomly chosen halves have similar |
interrater reliability | two diff observers' measurements similar |
validity | variable has been accurately measured and manipulated- logically appropriate |
construct validity | measurement must asses what you think you are measuring |
choose a task for which you will see a _______ of performance | range |
how to mislead with graphs | non-zero/diff scales/average values/log scale |
nominal scale calls for | mode |
standard error | s/√n |
operational definition | specific enough to replicate |
induction | specific to general |
morgan's canon | animals non anthropomorphed |
error variance | pooled |
converging operations | common conclusions |
types of measures | physiological/behavioral/self-reports |
