    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...

    1.) Recall that Benford's Law claims that numbers chosen from very large data files tend to have "1" as the first nonzero digit disproportionately often. In fact, research has shown that if you randomly draw a number from a very large data file, the probability of getting a number with "1" as the leading digit is about 0.301. Now suppose you are an auditor for a very large corporation. The revenue report involves millions of numbers in a large computer...
