Psyc355 - The t Test for Two Independent Samples

homogeneity of variance

assumption stating that the two populations being compared must have the same variance

Procedure for Using F-max Test: Step 3

comparison between F-max value and critical value

Procedure for Using F-max Test: Step 1

computation of the sample variance for each of the separate samples

Procedure for Using F-max Test: Step 2

computation using the largest and smallest of the sample variances

Hartley's F-max test

formula used to check whether two populations being compared have the same variance

independent-measures t statistic

formula used when separate groups of participants are used for each treatment condition

pooled variance

method correcting bias in standard error by combining two sample variances into a single value

repeated-measures research design

strategy in which two sets of data are obtained from the same group of participants

independent-measures research design

strategy using a separate group of participants for each treatment condition or for each population
