So you are asking Minitab to enter all values from 0 to 15 in the column C1. You will see the values appear in column C1. Next you use the probability distributions command (as described above) to compute the probabilities associated with the values in column C1, only that instead of using “input constant” box you use “Input Column” and select C1. For storage specify a different column, say C2. Press Ok. You will see the probabilities appear in column C2 in your worksheet. Unfortunately Minitab cannot draw the histogram of the data if it is given in two columns out of which one contains the probabilities associated with the values in the first column (or at least I haven’t found that out yet). Surprisingly enough this can be done with TI83. One way of getting the histogram of a binomial distribution is to generate random data following the given model and construct a histogram of the data generated. Here are the steps to do just that. We will generate 1000 values from a Binomial model with 15 trials and probability p=0.7 of success. That is, Minitab will generate 100 rows of data that will represent the number of successes out of 15 trials. Choose CALC- Random Data – Binomial. Enter the number of rows to generate (1000 in our case), specify the number of trials and the probability of success as well as the column where you want the data to be stored (C3 on our screen). Press OK. See screen shots on next page.
Then, using STAT – Basic Statistics – Display Descriptive Statistics you can perform the descriptive analysis of the data that was generated and you may add to it a graph (histogram of the data for example).
