You can compare the averages of multiple groups.
The one-way analysis of variance (one-way) ANOVA tests the null hypothesis that samples in three or more groups are drawn from the same population.
This App is useful for researchers, doctors, teachers, students, financial analysts, etc.
Before you like to use this analysis, you need to make sure that the variances of the groups are not different using Bartlett test. "BartlettTest", the App for iPhone/iPod touch, is also for sale in iTunes App Store.
