WebAug 28, 2024 · The t -distribution is a way of describing a set of observations where most observations fall close to the mean, and the rest of the observations make up the tails on either side. It is a type of normal distribution used for smaller sample sizes, where the variance in the data is unknown. The t -distribution forms a bell curve when plotted on a ... WebNov 28, 2015 · A very common thing to do with a probability distribution is to sample from it. In other words, we want to randomly generate numbers (i.e. x values) such that the values of x are in proportion to the PDF. So for the standard normal distribution, N ∼ ( 0, 1) (the red curve in the picture above), most of the values would fall close to somewhere ...
