You have a sample of data but are unsure what distribution it comes from. You plot it on 5 different types of probability paper to determine which has the best fit. Comparing the 5 different plots, how do you decide which distribution is the best fit? The plot with the straightest line is the best fit

Random Variables

A random variable Z is a real valued function of the type Z: S → R on a sample space S. That means the function assigns a real number to every primitive event in the sample space. In other words, a random variable is a function mapping a sample space S to a set of real numbers R.
