Introduction
The jewellery industry in India plays a vital role in cultural, social, and economic aspects of society. Jewellery is not only considered a fashion accessory but also a symbol of tradition, investment, and emotional value. With increasing competition among organized jewellery retailers, brands such as Kalyan Jewellers, Joyalukkas, and Malabar Gold & Diamonds have emerged as leading players in the market.
Understanding consumer reviews and satisfaction levels is crucial for jewellery brands to enhance service quality, product design, pricing transparency, and brand trust. Statistical tools like Analysis of Variance (ANOVA) are widely used to examine whether consumer reviews significantly differ across multiple brands. This study applies single-factor ANOVA to analyze consumer review ratings of selected jewellery brands.
Objectives of the Study
To determine whether the differences in consumer reviews are statistically significant using single-factor ANOVA.
Literature Review 1
Consumer Behaviour in Jewellery Retail
Previous studies indicate that consumer preference in the jewellery sector is influenced by factors such as purity assurance, brand reputation, pricing transparency, design variety, and after-sales service. Organized jewellery retailers have gained consumer trust by adopting hallmark certification and standardized pricing policies.
Literature Review 2
Brand Trust and Customer Satisfaction
Research suggests that strong brand image and ethical business practices significantly affect consumer satisfaction in the jewellery market. While different brands may emphasize varied promotional strategies and celebrity endorsements, overall customer satisfaction tends to depend on perceived value, service quality, and trustworthiness.
Data Collection
The study is based on primary data collected through a structured questionnaire. Respondents were asked to rate their overall experience with three jewellery brands on a numerical scale.
Each brand received 40 responses, resulting in a total sample size of 120 observations.
Variables Studied
Independent Variable: Jewellery brand (Kalyan Jewellers, Joyalukkas, Malabar Gold)
Dependent Variable: Consumer review rating score
Statistical Tool Used
Single-factor Analysis of Variance (ANOVA) was used to examine whether the mean consumer review ratings differ significantly among the selected jewellery brands.

Significance Level
- Level of significance (α) = 0.05
- F value < F critical
- P-value > 0.05
Hypothesis of the Study
Null Hypothesis (H₀)
There is no significant difference in the mean consumer review ratings of Kalyan Jewellers, Joyalukkas, and Malabar Gold & Diamonds.
Where:
μ₁ = Mean rating of Kalyan Jewellers
μ₂ = Mean rating of Joyalukkas
μ₃ = Mean rating of Malabar Gold & Diamonds
Alternative Hypothesis (H₁)
There is a significant difference in the mean consumer review ratings of at least one jewellery brand among Kalyan Jewellers, Joyalukkas, and Malabar Gold & Diamonds.
Decision Rule
- If P-value ≤ 0.05, reject the null hypothesis
- If P-value > 0.05, fail to reject the null hypothesis
Hypothesis Testing Result
Since the calculated P-value (0.329) > 0.05, the null hypothesis is accepted.
Conclusion of Hypothesis Test
The study reveals that there is no statistically significant difference in consumer review ratings among Kalyan Jewellers, Joyalukkas, and Malabar Gold & Diamonds.
Conclusion
The analysis indicates that consumers perceive all three jewellery brands as equally reliable and satisfactory in terms of overall experience. Although minor variations exist in individual ratings, statistical testing confirms that these differences are not significant. This suggests that brand trust, product quality, and service standards are consistently maintained across the selected jewellery brands.
