construct validity
accuracy in measuring what the study claims to measure
statistical validity

What is P-hacking
manipulating data or analysis until results are statistically significant
2x2 factorial design
2 IVs each with 2 levels
Main effect
the overall effect of one IV averaged across the levels of the other IV
interaction effect
the effect of one IV depends on the level of another
Why are interactions important?
they show moderation (if one variable changes the effect of another)
how are factorial designs used (in the real world)
test for moderation and replicate conditions
Reverse confound
a confounding variable that counteracts the real effect
Confounding variables
variable that varies with the IV and offers and alternative explanation
theory testing mode
focus on testing hypotheses in controlled conditions
what is situation noise?
uncontrolled environmental variability
within subjects design
all participants receive all levels of the IV
gold standard in psychology research…
double blind placebo controlled trials
