Statdisk Instructions for Chapter 2 Technology Exercise

Manipulating Data (Question 1)

1. Enter the five values into the first column
2. Go to Data / Descriptive Statistics
   1. Choose column 1
   2. Click Evaluate
   3. Type the values for the mean, median, range, standard deviation, and variance into the row labeled x in the table in Word
3. Go to Data / Sample Transformations
   1. The first transformation is a basic transformation. The source column is column 1, the operation is +, the constant is 30.
   2. Click Basic Transform
   3. Click Copy
4. Switch back to the sample editor window
5. Select Paste
   1. Paste the data into column 2
   2. Click OK
6. Go to Data / Descriptive Statistics
   1. Choose column 2
   2. Click Evaluate
   3. Type the values for the mean, median, range, standard deviation, and variance into the row labeled x+30 in the table in Word
7. Switch to the Sample Transformer window (or choose Data / Sample Transformer)
   1. Use a basic transformation of Column 1 divided by a constant of 10
   2. Copy the results
8. Switch to the sample editor
   1. Paste the results into column 3
9. Go to Data / Descriptive Statistics
   1. Choose column 3
   2. Click Evaluate
   3. Type the values for the mean, median, range, standard deviation, and variance into the row labeled x/10 in the table in Word
10. Switch to the Sample Transformer window (or choose Data / Sample Transformer)
    1. In the advanced transformation window, enter 5*(Col1-20)
    2. Click on Adv Transform
    3. Copy the results
11. Switch to the sample editor
    1. Paste the results into column 4
12. Go to Data / Descriptive Statistics
    1. Choose column 4
    2. Click Evaluate
    3. Type the values for the mean, median, range, standard deviation, and variance into the row labeled 5(x-20) in the table in Word

Answer the questions in general terms, not specifically based on the examples used. For example, if you notice that the mean is 30 more when you add 30 to all the values, don't say that, say something like "When you add a constant to all the values, that same constant is added to the mean." Don't limit yourself to just the 30.

Pie Chart (Question 2)

The pie chart capability in Statdisk is very limited and unfriendly to certain people. It conveys information by color alone and that should never be done as color blind people can't tell the difference.

Furthermore, there is no easy way to copy and paste a graph in Statdisk. You have to press the Print Screen key, but that captures the entire screen, not just the window with the pie chart.

Use Minitab to create the pie chart!

Graphical Summary (Question 3)

The graphical summary for Statdisk isn't half bad, but there's no easy way to copy and paste a graph into Word.

Use Minitab to create the Graphical Summary!
