Document Summary

We often use an experimental design in which measurements on a single dv are repeated a number of times within the same subject. Such designs in which subjects are crossed with at least one experimental factor are called repeated-measures designs. The simplest experiment of this kind may be a before- and after-treatment design (two conditions) One-way means the number of independent variables is one. N subjects are measured on a single dv under k conditions or levels of a single iv or factor. Subjects are repeatedly measured across all levels of independent variables. This factor has multiple levels k is the amount of levels. Example: class row there are three levels of class row. This is the same independent factor, but separated into several groups. Dv: for example, this could be exam scores k different groups have different subjects. We assume that all groups have different subjects in regular one-way anova.
