WebMar 1, 2024 · Many statistical tests make the assumption that the values in a dataset are normally distributed. One of the easiest ways to test this assumption is to perform a Jarque-Bera test, which is a goodness-of-fit test that determines whether or not sample data have skewness and kurtosis that matches a normal distribution. WebThe Central Limit Theorem lets us use the normal theory inference (t-tests in this case) even if the population is not normally distributed as long as the sample sizes are large enough. This does mean that your test is approximate (but with your sample sizes, the appromition should be very good).
