1. OBJECTIVE OF THE STUDY
- To analyse customer satisfaction levels across different smartphone brands
- To compare the mean satisfaction scores of major smartphone brands
- To apply One-Way Analysis of Variance (ANOVA) to examine differences among brands
- To determine whether the differences in customer satisfaction are statistically significant
2. LITERATURE REVIEW
Customer satisfaction plays an important role in influencing brand loyalty and repeat purchase behaviour in the smartphone industry. Previous research highlights that factors such as product quality, pricing, brand image, and user experience significantly affect satisfaction levels. ANOVA has been widely used in consumer behaviour studies to compare satisfaction levels across multiple brands due to its effectiveness in identifying mean differences.
3. HYPOTHESIS
Null Hypothesis (H₀):
There is no statistically significant difference in customer satisfaction levels among the selected smartphone brands.
Alternative Hypothesis (H₁):
There is a statistically significant difference in customer satisfaction levels among the selected smartphone brands.
4. DATA COLLECTION
The study is based on primary data collected through a structured questionnaire. Respondents rated their satisfaction levels for Apple iPhone, Samsung, OnePlus, and Xiaomi on a 1–10 scale, where higher scores indicate greater satisfaction. The collected data were coded and analysed using Microsoft Excel.
5. DATA ANALYSIS
One-Way Analysis of Variance (ANOVA) was used to test differences in customer satisfaction levels among the selected smartphone brands. The results indicate that the F-value for brands (0.338) is lower than the F-critical value (3.117), with a p-value of 0.714, which is greater than the 0.05 significance level. Therefore, the null hypothesis is accepted, indicating no statistically significant difference in satisfaction levels among the selected smartphone brands.
6. CONCLUSION
The study concludes that customer satisfaction levels across Apple iPhone, Samsung, OnePlus, and Xiaomi are statistically similar. This suggests that consumers perceive these brands at a comparable level of satisfaction. The findings provide useful insights for smartphone manufacturers in maintaining competitive strategies. The study is limited by sample size and methodology; future research may consider a larger sample and additional variables for deeper analysis.
