Document Summary

You do not want this variable in your study because it prevents you from making conclusions. A variable that interferes with the results of the study. It affects the d. v. , so you don"t know whether the results are caused by the i. v. or by the confounding variable. Ex: a group of people study a certain amount of hours: one studies 0, one studies 5, and one studies 10 hours. The one which studied 10, and the one which studied 0 both got the same results because the first group did not get any sleep. For experiments, you don"t randomly pick from population, you take people who are willing to participate and then randomly assign them to groups. Random sampling for survey and random assignment for an experiment. Measures how closely connected two variable are. Scatterplot can be used to plot the correlation.
