Last time we took a look at the chi-squared distribution which describes the behaviour of sums of squares of standard normally distributed random variables, having means of zero and standard deviations of one.
Tangentially related is Student's t-distribution which governs the deviation of means of sets of independent observations of a normally distributed random variable from its known true mean, which we shall examine in this post.
