2012-09-17В В· Applications Of Chi Square Distribution. if you have normally distributed data and want to test a hypothesis, you can calculate a quantity, which is big when the data doesn't fit the hypothesis and small when the data fits the hypothesis. That quantity is most often chi-square distributed. A more preferable test statistic is HotellingвЂ™s T 2 and we will focus on this test. To motivate Hotelling's T 2, consider the square of the t-statistic for testing a hypothesis regarding a univariate mean. Recall that under the null hypothesis t has a distribution with n-1 degrees of freedom.
