pearsonUnit 9: Hypothesis Testing Goal: rule out chance (sampling error) as a plausible explanation for the results from a research study Significance testing Hypothesis: statement about value/size of population parameter that needs verification Hypothesis testing: based on sample evidence and probability theory 1. Null (H0) and alternative (H1) hypothesis: statement about value of population parameter, not sample a. Mutually exclusive and collectively exhaustive b. H0 always presumed to be true (“innocent”): = >= <= (equality) c. H1 burden of proof (“guilty”): > < ≠ (inequality) d. Random sample “n” is used to reject H0 e. Conclude do not reject H0: not enough evidence to reject H0 (NOT that H0 is true)
