Problem 109E

Consider the following two sample data sets, saved in the LM2_132 file:

a. Construct a box plot for each data set.

b. Identify any outliers that may exist in the two data sets.

Step-by-Step Solution:

Step 1 of 2

(a)

Consider the following two sample data sets.

 Sample A Sample B 121 171 158 171 152 170 173 184 163 168 169 171 157 85 145 190 183 185 165 172 196 140 173 206 170 159 172 172 174 169 161 187 100 199 151 180 142 166 171 167 170 188

We need to construct a boxplot for each data set.

Using Minitab, the box plot for sample  is given below:

Step to create the box plot in Minitab:

1. On the opening of Minitab, you will get session handler and worksheet like Excel worksheet.
2. Enter the data into the worksheet (in this case Sample A).
3. After entering the data go to a menu called Graph in menu panel.
4. In the Graph menu select option Box Plots, you will get one window of Boxplots.
5. Under the Boxplots window,  and select the simple graph option.
6. After doing this, you will get another which will contain all the variables you have entered in the worksheet.
7. Select the Sample A variable as Graph variables.
8. After everything entered correctly, press ok and you will get the Boxplot of your data.
9. Right click on the graph you have just created and select the copy graph option.
