Document Summary

Confounding variable: a variable that interferes with the results of the study. It affects the dv so you don t know whether the effects are caused by the iv, the confounding variable, or both. Random assignment to the groups y by randomly assigning people to groups you are assuming that all individual difference variables are being evenly distributed among groups so that the groups are essentially the same. Correlation the relationship between two variables y y there s no attempt to manipulate and control variables rather naturally occurring variations in both variables are measured to see if they re related r= +or- numbers numbers: strength of relationship. Numbers on vary from 0 to 1. 00 (1. 00 is perfect) If you get a + the values of both variables are changing to the same direction. If you get a the values of both variables are changing to the opposite direction.
