Objective: To compare the likeability of bike brands
1. TVS
2. Honda
3. Yamaha
4. Bajaj
Test Hypothesis: H0 all are same, H1 at least one of them is different.
Data Collection: Four bike 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.
Data analysis:
Anova: Single Factor
SUMMARY
Groups Count Sum Average Variance
TVS 40 273 6.825 6.660897
Honda 40 295 7.375 5.112179
Yamaha 40 303 7.575 5.378846

ANOVA
Source of Variation SS df MS F P-value F crit
Between Groups 14.2 3 4.733333 0.82328 0.482871 2.662569
Within Groups 896.9 156 5.749359
Total 911.1 159
The ANOVA table shows that the “Between Groups” factor has a sum of squares (SS) of 14.2, a degree of freedom (df) of 3, and a mean square (MS) of 4.733333.
The “Within Groups” factor has an SS of 896.9 and a df of 156, resulting in an MS of 5.749359.
The F-ratio calculated by dividing the MS for the “Between Groups” factor by the MS for the “Within Groups” factor is 0.82328, which corresponds to a P-value of 0.482871.
The P-value associated with the F-ratio is 0.482871, which is greater than the conventional threshold of 0.05. This indicates that there is no 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 2.662569. The obtained F-ratio is smaller than the critical F-value, indicating that there is no significant difference between the means of the groups.
H0 accepted.
Conclusion: All are the same.
