One-Way ANOVA, Rating Analysis of 4 Wearable Audio Devices
Author – Ajinkya P. Sherki (0225048)
Introduction
The increasing use of wearable audio devices has transformed consumer listening habits and preferences. Products such as TWS earphones, over-ear headphones, neckbands, and wired earphones differ in terms of convenience, sound quality, and usability. Understanding how consumers perceive these devices is important for effective product positioning and marketing strategies. This study collects user ratings on a scale of 1 to 10 to evaluate their preferences. A one-way ANOVA is applied to determine whether significant differences exist among the mean ratings of these device categories.
Objective: To compare 4 Wearable Audio Devices by One-Way ANOVA.
Literature Review
According to Philip Kotler and Kevin Lane Keller (2016), consumer preferences are shaped by perceived value, product features, and convenience, which are key factors influencing the choice of wearable audio devices.
Ronald A. Fisher (1925) introduced Analysis of Variance (ANOVA) as a statistical method to compare means across multiple groups, making it a suitable tool to analyse differences in consumer preferences among various product categories.
Data collection
Students of our Batch were requested to grade the following Wearable Audio Devices: TWS earphones, over-ear headphones, neckbands, and wired earphones, on a scale of 1-10. The Google Form was circulated in class, and a one-way ANOVA was calculated.
Data analysis
H0: TWS earphones=over-ear headphones=neckbands=wired earphones
H1: Any one of them is different
Mean Square Between (MS): 5.24; Mean Square Within (MS): 3.8075; P-value: 0.2547; df: (3, 96) (Between Groups, Within Groups); F crit: 2.6994

Conclusion
The p-value= 0.2547 is greater than the significance level of 0.05, which means all wearable audio devices are the same.
