MINITAB INSTRUCTIONS FOR SIMPLE LINEAR REGRESSION
To construct a scatterplot:
1. Click on the Graph button in the menu bar. Select Plot.
2. Make the appropriate variable selections and click OK to view the graph.
Note: It is sometimes interesting to look at the spread of different groups (for example,
distribution of males vs. females.) To do this, return to the Plot dialogue box. In the Data
display section, go to the For each drop-down box and select Group. Then move to Group
variables and enter the name of the column that contains the group variable.
To construct a fitted line plot (and, in turn, a simple linear regression analysis):
1. Click on the Stat button in the menu bar. Select Regression  Fitted Line Plot.
2. Make the appropriate variable selections (place the cursor in the box where you wish to
add a variable, highlight the variable in the box to the left, then click Select. The
dependent variable belongs in the Response box, and the independent variable belongs in
the Predictor box.) Finally, click OK.
To conduct a regression analysis:
1. Click on the Stat button in the menu bar. Select Regression  Regression.
2. Make the appropriate variable selections (place the cursor in the box where you wish to
add a variable, highlight the variable in the box to the left, then click Select. The
dependent variable belongs in the Response box, and the independent variable belongs in
the Predictors box.) Finally, click OK.
