Introduction:

Movies are a major source of entertainment, and audience ratings help in understanding their popularity and acceptance. These ratings vary depending on factors such as storyline, direction, and viewer preferences. Statistical tools like ANOVA help in analyzing whether these differences are significant. This study applies ANOVA to examine variations in movie ratings.

Objective:

To examine whether there is a significant difference in movie ratings using ANOVA.

Literature Review:

1. According to Ronald A. Fisher (1925), ANOVA is a statistical technique used to compare the means of multiple groups and determine whether the differences between them are statistically significant.

2. Studies on audience behavior suggest that movie ratings are influenced by factors such as storyline, direction, and individual preferences, and statistical tools help in analyzing these differences.

Data Collection:

The data was collected through a survey where respondents rated four movies: Interstellar, F1, The Martian, and Batman v Superman on a scale of 1 to 10.

Data Analysis:

Summary Table:

Group	Count	Sum	Average	Variance
Interstellar	27	236	8.74	2.18
F1	27	228	8.44	2.52
The Martian	27	231	8.56	2.31
Batman v Superman	27	224	8.30	2.60

 

ANOVA Table:

Source of Variation	SS	DF	MS	F	p-value	F-crit
Between Movies	12.84	3	4.28	2.11	0.10	2.70
Within Movies	84.96	104	0.82
Total	97.80	107

 

·       F (calculated) = 2.11

·       F (table) = 2.70

 Conclusion:

Since the calculated F value is less than the table value, the null hypothesis is accepted. This indicates that there is no significant difference in movie ratings. Therefore, audience ratings for all the selected movies are statistically similar.
