It is expressed as a number in the range from 0 and 1, or, using percentage notation, in the range from 0% to 100%. So I would say that, um, they each of different levels of skewed nous. The sampling distribution of the sample mean based on samples of size 2 for the population was simulated, and a histogram of the results was produced. Below are histograms of the values taken by three sample statistics in several hundred samples from the same population. A rule of thumb is to use a histogram when the data set consists of 100 100 values or more. B.
