1. A basic tutorial

2. What we will do Import Data from Excel Basic statistics
Plots (box and scatter)
Capability Analysis

3. About the data The data represents
Time to complete the project (this is a y variable- a measure of performance).
The maximum (USL) is 30.
Work effort to complete the project (this is a y variable – a measure of performance)
The maximum (USL) is 600
Two “teams” that performed the project (these are x variables – inputs)
These are categorical variables
The complexity of the project - an index based on the number of tasks and how complex they are for this project (it’s a type of input, a descriptive input, so an x variable).

4. Importing from Excel Open Excel and Minitab
Go to the Minitabdata15 Excel file.
Go to sheet data3
Select the data including the headers in Excel.
Click on Copy.
Paste in Minitab
