Description: Learn the difference between Z, T, Chi-square and F statistics! This video will cover what each of these statistics are and the common thread shared between each of them. This tutorial explains what each the Z statistic, T statistic, Chi-square statistic and F statistic are and where they come from. The z-statistic is the base statistic you use for the normal distribution. The t-statistic is a more conservative version of the z-statistic when you don't know a population's standard deviation. The chi-squared statistic is a sum of multiple squared z-statistics. The f-statistic is the ratio of two chi-square values.
