Overview—Chi-Square: Lecture 11 (00:36)


In this lecture, Prof. Naomi Lowe explains the types of chi-square, tests of chi-squares, and how articles report the chi-square statistic.

Types of Variables and Goodness of Fit (14:57)

Use a chi-square when you have a nominal variable. Learn the formula that tests the predetermined fit of the difference categories of a single variable. Determine degrees of freedom and cut-off, and accept or reject the null.

Independence (11:11)

When using two nominal variables that have several categories, examine whether there is a relationship between the variables; create a contingency table. Calculate expected values and compare chi-square test statistic to chi-square distribution cut-off. Use phi for effect size in a 2x2 contingency table, and Cramer's Phi for larger tables.
