Calculate one-way Analysis of Variance (ANOVA) to compare means across three or more groups

Group 1 Data (comma-separated):

Group 2 Data (comma-separated):

Group 3 Data (comma-separated):

ANOVA (Analysis of Variance) tests whether the means of three or more groups are significantly different.

Null Hypothesis: All group means are equal

F-Statistic: F = MSB / MSW

A large F-statistic suggests that group means are different. Compare with F-distribution critical values to determine significance.
