Objective: To compare the rating of 4 Car Brand Companies.
Data Collection: Recently, I conducted a survey through Google Forms to explore ratings given to 4 Car brand Companies. With responses from students, got an understanding which Company is favoured by students. The rating was given on scale of 1 to 10 of 4 Car brand Companies.
Data Analysis: The ANOVA: Single Factor test was performed to compare the means of the ratings across the four genres.
The hypotheses for the test are:
- Null Hypothesis (H0): There is no significant difference in the average ratings of Car brands.
- Alternate Hypothesis (H1) At least one of the genres has a significantly different average rating.
The results of the ANOVA: Single Factor test are as follows:
| ANOVA | ||||||
| Source of Variation | SS | df | MS | F | P-value | F crit |
| Between Groups | 26.88888 | 3 | 8.96296 | 1.68776 | 0.17419 | 2.69197 |
| Within Groups | 552.29629 | 104 | 5.31054 | |||
| Total | 579.18518 | 107 |
Above table shows P value as 0.17 which is more than 0.05 which means Alternate Hypothesis is not accepted.
Conclusion: Anyone of them is not different.
