# Minitab Notes for Activity 2

## Creating the Worksheet

- Label two columns with the first names of the people in your group.
- Enter the distances from the target to the center to the washer in each
column

## Summarizing the Data (Question 2)

Do this as a check. I want you to find the values asked
for by hand as practice for the test.

Minitab does not find the variation for you. Another name for Variation is
Sum of Squares, but the Sum of Squares under the Statistics box is the uncorrected
sum of squares, which is what you get if you just square the values and add
them up, not the value we want which is found by subtracting the mean before
squaring the values.

- Choose Stat / Basic Statistics / Display Descriptive Statistics
- Double click on your two variable names
- Click on Statistics
- Turn on the box for Variance
- Turn off the box for N Missing and SE Mean
- Click OK

- Click OK

You should get some output that looks like this.

**Descriptive Statistics: john, sue**
Variable N Mean StDev Variance Minimum Q1 Median Q3 Maximum

john 6 6.267 2.242 5.027 3.400 4.375 5.900 8.725 9.100

sue 5 5.500 1.214 1.475 4.100 4.500 5.200 6.650 7.300

Check the sample size, mean, median, variance, and standard deviation
with what you calculated by hand.
