The ANOVA test uses the F statistic. The formula for the test statistic is given as F = mean squares between groups (MSB) / mean square between errors (MSE) What is an ANOVA Table? An ANOVA table is a table that is used to summarize the findings of an ANOVA test. There are 5 colu...

Analysis of variance (ANOVA) is a statistical test used to compare the means of multiple groups. Learn what is ANOVA, its formula, types, applications, etc.
The p-value is the probability that the test statistic can take a value greater than the value of the computed test statistic, i.e., P(F > 6.05). The small p-value of 0.0023 indicates that differences between column means are significant. Compare Beam Strength Using One-Way ANOVA Copy ...

The ANOVA test lets you compare more than two groups simultaneously to determine whether a relationship exists between them. The result of the ANOVA formula, the F statistic or F-ratio, allows you to analyze several data groups to assess the variability between samples and within samples. If no...
