value, critical values How do you find the corresponding t
score (critical/cutoff value)? What information is needed to determine the critical value on a t table? If we get a result more extreme then the t

directional hypotheses; One
tailed vs. two
tailed tests Know how to select the appropriate approach for your research hypothesis Effect size Calculation for Estimated d (effect size) for t test of independent means Be able to interpret effect size based on conventional cut

What influences power (i.e., what is represented in a power table)? Be able to use a power table to: Plan a study (e.g., Determine needed number of participants) Evaluate non
significant results of study (e.g., Was there enough power?) Reporting results Understand how to interpret the results of a t test that are reported in a table or in words, as would be done in a research article....
