“An ANOVA based comparison of Listeners ratings for music genres”
– Arya Patil (21331025076)
Introduction
Music preferences vary significantly among individuals and are influenced by factors such as mood, culture, age, and personal taste. Different music genres evoke different emotional and psychological responses, leading listeners to rate them differently. This study aims to compare listeners’ ratings across various music genres using Analysis of Variance (ANOVA). By examining whether mean ratings differ significantly among genres, the study provides insights into listener preferences and patterns of music appreciation.
Objectives of the Study
- To analyse listeners’ ratings for different music genres using a numerical rating scale.
- To compare the mean ratings of various music genres using ANOVA.
- To identify whether significant differences exist in listener preferences among music genres.
- To understand patterns and trends in audience appreciation across genres.
- To provide insights useful for music producers, streaming platforms, and marketers.
Literature Review
According to North and Hargreaves (2007), music preference is a complex phenomenon influenced by social identity, emotional needs, and situational factors. Their research suggests that listeners tend to rate genres higher when they align with their personal values and emotional states. This indicates that genre-based differences in listener ratings are both measurable and meaningful.
Rentfrow and Gosling (2003) examined the relationship between music preferences and individual characteristics, finding significant variation in how different genres are perceived and rated. Their study supports the use of statistical techniques such as ANOVA to compare genre-wise listener ratings, as preferences differ substantially across musical styles.
Data Collection
Primary data was collected from respondents to analyze listeners’ ratings for different music genres. The respondents were asked to rate each music genre based on their personal liking and listening experience.

Interpretation
The calculated F-value (0.16) with a p-value of 0.958 is greater than the conventional significance level of 0.05. Hence, there is no statistically significant difference in the mean ratings given by listeners across different music genres.
This indicates that listeners rated the genres fairly similarly, and variations in ratings are likely due to random factors rather than genre-based preference differences.
Hypothesis Testing
Null Hypothesis (H₀):
There is no significant difference in the mean ratings given by listeners for different music genres.
Alternative Hypothesis (H₁):
There is a significant difference in the mean ratings given by listeners for different music genres.
Decision Rule:
The null hypothesis is rejected if the p-value is less than 0.05.
Result:
Since the p-value obtained from the ANOVA test (p = 0.958) is greater than 0.05, the null hypothesis is accepted.
Inference:
There is no statistically significant difference in listeners’ ratings across the selected music genres.
Conclusion
The ANOVA-based analysis of listeners’ ratings for various music genres reveals that there is no significant difference in the average ratings assigned to each genre. Although individual preferences may vary, the overall listener ratings across genres such as Pop, Rock, Classical, Jazz, and Hip-Hop appear to be similar. The findings suggest that listeners show a balanced appreciation toward different music styles rather than a strong preference for any single genre. This study highlights the subjective nature of music perception and indicates that multiple genres are equally valued by listeners.
