In this video, we begin to make inferences about variances. To begin I offer several short, real-world scenarios where variance becomes important in its own right. Next, we compare the sampling distribution of sample means to the sampling distribution of variances. This leads us to a new distribution; the chi-square distribution. We end by learning how to find critical values in the chi-square table. Enjoy!
