Description: Learn how to solve any Chi-Square Test for Goodness of Fit problem! This tutorial explains when to use a chi-squared test for GOF, how it differs from 1 or 2 sample z-tests for proportions and the process to follow to solve any of these types of hypothesis test questions. In this video, you will follow the 5 C's to solve this type of hypothesis test. These steps can be followed for any test no matter whether it is a 1 sample z test, 1 sample t test, 2 sample z test, 2 sample t test, ANOVA test, chi-squared test, etc. First, we CREATE our hypotheses. Then we CHECK 3 conditions are true in order to prove our data is a good sample of our population. Next, we CALCULATE our test statistic, chi-squared, and p-value. Then we COMPARE this p-value to our significance level (or alpha value). And finally we CONCLUDE based on this comparison. This video goes over the high level process and shows how it works with an in depth example problem.
