One way Anova Confirmation run

The One way Anova Confirmation run calculates if the mean of at least one dataset is significant different. The calculation calculates the anova only from the checked data sets in the anova dialogue.

Interpretation

• The smaller the p value is the more likely there is a dataset with a significant difference.
• In Develve for a significant difference the p value must be below 0.05.
