How is ANOVA Conducted in Epidemiological Studies?
The basic steps to conduct ANOVA in epidemiological studies are as follows:
Define the Null Hypothesis (H0): Assume that there are no differences in the means among the groups. Calculate the Mean Squares: Compute the mean squares for both between-group and within-group variances. Calculate the F-Statistic: The F-statistic is the ratio of the between-group mean square to the within-group mean square. Compare the F-Statistic to the Critical Value: Determine the significance by comparing the F-statistic to a critical value from the F-distribution table. Interpret the Results: If the F-statistic is higher than the critical value, reject the null hypothesis, indicating that there are significant differences between group means.
