Result –
The sum of squares (SS) between the groups is 104.66, within the groups is 1005.92, and the total is 1110.59
The degree of freedom (df) between groups is 3, within the groups is 156, and the total is 159.
The mean sum of squares (MS) between groups is 34.88, within the groups is 6.44.
The F-ratio is 5.41.
The p-value is 0.001, which means that the result is statistically significant.
The critical F-value (F-crit) at a significance level of 0.05 with 3 and 156 degrees of freedom is 2.662.
Based on the F-ratio, which is much larger than the critical F-value, and the p-value, which is less than 0.05, we can reject the null hypothesis and accept alternate hypothesis.
