One-Way ANOVA Step-by-Step Example
Imagine you manufacture paper bags and you want to improve the tensile strength of the bag. You suspect that changing the concentration of hardwood in the bag will change the tensile strength. You measure the tensile strength in pounds per square inch (PSI). So, you decide to test this at 5%, 10%, 15% and 20% hardwood concentration levels. These "levels" are also called "treatments."
To perform One-Way ANOVA in Excel using QI Macros follow these steps:
- Click and drag over your data to select it:
- Now, click on the QI Macros menu > Statistical Tools > ANOVA - Analysis of Variance, and select "ANOVA Single Factor":
- QI Macros will prompt you for the significance level you desire. The default is 0.05 (95% confident).
- QI Macros will perform the calculations and analyze the results for you:
Interpreting the Results of a One-Way ANOVA Test
When you run ANOVA, you don't have to think like a statistician because QI Macros interprets the results for you. QI Macros is the only statistical software that tells you if you can Reject the null hypothesis or Cannot Reject the null hypothesis (Accept the null hypothesis) and whether the Means are the same/Means are not different or Means are different/Means are not the same.
In the example above, QI Macros built in code compares the p-value (0.000) to the significance (0.05) and tells you to "Reject the Null Hypothesis because p<0.05 (Means are Different)."
QI Macros also draws a box plot to help you visualize the results. Compare the difference in Means (color change in the box) and the variation (height of the box and length of the whiskers).
