One measure of variation that we can look at is the Range when we have continuous variables. We will be using this measure to create a histogram. A histogram is used to show the frequencies of certain events or categories of data values in a set of data from one time period. Data are plotted in increasing or deceasing order based on the frequency count for each data categories. Assignment I Below is a data file containing the average number...
