Objective: To compare the likeability of Watch Brands
1. Rolex
2. Seiko
3. Casio
4. G Shock
Test Hypothesis: H0 all are same, H1 at least one of them is different.
Data Collection: Four best cartoon brands were selected for this Project: One Way ANOVA.
Students of the class were requested to grade the brands out of 10 and then One Way
ANOVA was calculated.

The ANOVA table shows that the “Between Groups” factor has a sum of squares (SS) of
46.26875, a degree of freedom (df) of 3, and a mean square (MS) of 15.42291667.
The “Within Groups” factor has an SS of 775.175 and a df of 156, resulting in an MS of
4.969070.
The F-ratio calculated by dividing the MS for the “Between Groups” factor by the MS for the
“Within Groups” factor is 3.10379, which corresponds to a P-value of 0.028338262.
The P-value associated with the F-ratio is 0.028338262, which is smaller than the
conventional threshold of 0.05. This indicates that there is a significant difference between
the means of the groups.
The critical F-value for this analysis, based on a significance level of 0.05 and the degrees of
freedom for the “Between Groups” and “Within Groups” factors, is 2.662568549. The
obtained F-ratio is greater than the critical F-value, indicating that there is a significant
difference between the means of the groups.
H1 accepted.
Conclusion: At least one of them is different.
