Appendix 10.1 ■ Experimental Design and Analysis of Variance
Using Excel
The instruction blocks in this section each begin by describing the entry of data into an Excel spreadsheet. Alternatively,
the data may be downloaded from this book’s website. Please refer to Appendix 1.1 for further information
about entering data, saving data, and printing results when using Excel.
One-way ANOVA:
•
Enter the gasoline mileage data as follows:

mileage values in cells A2 to A6; type the label
“Type B” in cell B1 with its five mileage values
in cells B2 to B6; type the label “Type C” in cell
C1 with its five mileage values in cells C2 to C6.
