Understanding ANOVA: Extending Beyond t-Tests in Sample Mean Comparisons

ANOVA (Analysis of Variance) is a powerful statistical method akin to the t-test, employed to compare means across multiple samples. Unlike the t-test, which can only compare two groups, ANOVA allows for the assessment of three or more sample means simultaneously to determine if they differ significantly. When the null hypothesis is rejected, it is critical to conduct follow-up tests to identify which specific groups are different. This method is widely used in various research fields to analyze complex data sets effectively.
