# Question:

Effect Size

indicates the magnitude of a relationship.
An effect size of zero indicates there is no relationship between the variables and alrger (postive) effect sizes indicate stronger relationships
Effect size can only be esitmated based on previous research
Estimates are usually based on Cohen's recommendations
small effect = .10
medium effect = .30
Large effect = .50

the smaller your expected effect size is, the harder the relationship will be to detect
