Assignment 2: Chi SquarePreviously in this course, you worked with parametric staTsTcs like t-tests, ANOVAs, and correlaTons. Inorder to use parametric procedures such as those, the dependent variable must be measured on eitheran interval or a raTo scale. SomeTme, however, the variables of interest are categorical; that is, they arenot measured on an interval or a raTo scale. For example, the categorical variables of gender, race, orpoliTcal a±liaTon are not measured with interval or raTo scales. For this Assignment, you will examinethe nonparametric procedure called chi square, which allows you to analyze categorical data.²o prepare for this Assignment, imagine that you have informaTon about how 20 nursing students and20 psychology students felt about starTng PSYC 3002 on Day 1 of this class.
