Document Summary

Z-test single score: state null + research hypothesis, calculate z with formula, look up in z chart p(larger or smaller portion, reject null hypothesis if p . 05. T-test single score: state null + research hypothesis, specify 1- or 2-tailed test, alpha (. 05, calculate df (n-1), , sx: fill in t df equation (t obs , look up df and alpha . 05 in t table to find t crit, compare t obs to t crit (t obs > t crit to reject null hypothesis, report findings as t(df) = t-score. Paired samples t-test (differences scores): calculate difference scores (score 1 - score 2 = difference, state null + research hypothesis, specify 1- or 2-tailed test, alpha (. 05, calculate mean of difference scores ( Independent t-test: and s for each sample: state null + research hypothesis, specify 1- or 2-tailed test, alpha (. 05, calculate.
