Author– Tejas Waghmare
INTRODUCTION: This research aims to evaluate customer satisfaction across four popular Indian soap brands—Lux, Lifebuoy, Pears, and Santoor—using a one-way ANOVA analysis. By collecting satisfaction ratings from 30 customers, we assess whether differences in satisfaction between the brands are statistically significant.
OBJECTIVE: To analyse the relationship between four variables Lux, Lifebuoy, Pears, and Santoor
DATA COLLECTION: The data for this study was collected from 30 customers who rated their satisfaction with four Indian soap brands: Lux, Lifebuoy, Pears, and Santoor. A survey was used to gather customer ratings on a scale of 1 to 10, with higher scores indicating greater satisfaction. The sampling method was convenience-based, relying on the availability of respondents. Each participant provided ratings for all four brands based on their personal experiences. The data was then organized into a table format in Excel for further analysis using one-way ANOVA.

Hypothesis:
Null Hypothesis: There is no significant difference in the mean scores among the four soap groups (Lux, Lifebuoy, Pears, and Santoor).
Alternative Hypothesis: Given the p-value of 0.385214, we would fail to reject the null suggesting that there are no significant differences in the mean scores of the soaps.
Conclusion: The one-way ANOVA analysis was conducted to compare customer satisfaction ratings for four different Indian soap brands: Lux, Lifebuoy, Pears, and Santoor. With a p-value of 0.3852 (greater than 0.05), the results suggest that there is no statistically significant difference in customer satisfaction between the four brands. Therefore, we fail to reject the null hypothesis, concluding that the brands are perceived similarly by the customers in terms of satisfaction.
