Pie Charts and Bar Charts on Directors of Three Stooges Films Probability and Statistics (MATH 1530) Worksheet, Gardner and Davidson, Spring 2009 The purpose of this worksheet is to help familiarize you with Minitab. You are given step-by-step instructions on exactly what commands to give Minitab in order to produce a pie chart and a bar chart based on data concerning the directors of the films of the Three Stooges. Answer all questions (which appear in red) in complete sentences – you are trying to convince me that you understand the material and that you can communicate your understanding clearly. The Three Stooges had a number of different directors In the 190 films that they made with Columbia Pictures between 1934 and 1959. Here is a table of data which includes several of the directors, along with the number of films they directed: Director # of Films Directed Del Lord 39 Preston Black 7 Charles Chase 5 Jules White 104 Edward Bernds 25 Other 10 You will create a pie chart and a bar graph which reflects the information in this table. You will then be asked a few questions about the results. Start Minitab by clicking on the start button at the lower left of the screen. From All Programs, choose Statistical Programs and find Minitab in the list. Once Minitab starts, you will see a mostly clear white window at the top labeled Session and a lower window labeled Worksheet 1. You will enter the data in the worksheet window. Here are the steps to enter the data. In column 1 (C1) enter the directors’ names in the cells (order does not matter). You can use the edit keys (the four keys with the arrows on them) to move between cells. The name of the column will change to C1-T since you have entered text in that column. Then enter the number of films directed by each person in column 2 (C2) in the corresponding position. You now have the data (both categorical and quantitative). Here are the commands to create the pie chart. Click on the Graph tab and select Pie Chart from the pull down menu. Select “Chart values from a table.” Click in the “Categorical variable” box, click on C1 in the left hand box and then click on the Select button. Click in the “Summary variables” box, click on C2 in the left hand box and then click the Select button again. Minitab now has the information it needs to create a pie chart. However, let’s make it look nice! To enter labels for the pie slices, click Labels and enter a title in the appropriate place. While still in the Labels menu, click on the “Slice Labels” tab and under “Label pie slices with” select “Category name.” Click OK. Minitab now has the data, the title, and the labels it needs to create the desired pie chart. Click OK and Minitab will create the pie chart. Now you will insert the pie chart into this Word document. Increase the size of the window containing the pie chart. What happens when you put the mouse arrow over a region of the pie chart? Insert your answer here (in complete sentences). A small window pops up with that region (slice or sector) of the pie as a percentage of the whole pie, reflecting the percentage of the data which falls in the corresponding category. Click on the File tab and select “Save Graph As.” In the “Save As” menu, change the “Save as type” to a graphics format (such as JPG or BMP). Change the “Save in” and “File name” information until it is what you want (be careful to save the file in a place you can find it). Do not close Minitab, since you will make a bar chart using the same data you have already entered. Now, while in Word, use the Insert tab to insert a Picture, “From File” to put the pie chart here:
