1. Introduction
The global smartphone market is highly competitive, with brands striving to differentiate themselves through innovation, performance, design, and after-sales service. Consumer perception plays a critical role in determining brand success, as purchasing decisions are strongly influenced by user experience and brand reputation. This study focuses on four leading smartphone brands—Apple, Samsung, OnePlus, and Xiaomi—to evaluate whether there are statistically significant differences in consumer ratings among them. A One-Way ANOVA technique is used to objectively assess whether variations in consumer satisfaction are meaningful or occur due to random variation.

3. Objectives of the Study
Previous studies indicate that smartphone purchase behavior is influenced by factors such as brand image, operating system, performance, camera quality, and price-value ratio (Kotler, 2022). Apple is often associated with premium branding and ecosystem integration, while Samsung is known for innovation and display technology. OnePlus has gained popularity for high performance at competitive prices, and Xiaomi is recognized for value-for-money offerings. Statistical tools like ANOVA are widely used in consumer
4. Data Collection
The data collection process for this study was structured to facilitate a comparative analysis across the luxury segment.
- Sample Selection: The dataset consists of 164 unique consumer observations. To ensure a balanced ANOVA, the sample was equally distributed among four brands: Oneplus , Apple, Nothing,Sony.
- Sample Size per Group: Each brand was evaluated by 41 respondents ($n=41$), ensuring consistency in the weight of each group during calculation.
- Measurement Variable: The primary data point collected was the “Consumer Rating.” This is a quantitative, discrete variable recorded on a scale of 1 to 10.
- Data Structure: The data was organized into a matrix format where each column represents a specific smartphone brand. This structure is designed for “Single Factor ANOVA,” where the “Brand” is the independent variable (factor) and the “Rating” is the dependent variable.
- Data Integrity: The ratings show a wide range of variance (ranging from 1 to 10), reflecting a diverse pool of consumer opinions rather than a skewed or biased sample.

Interpretation
Ø Average Ratings: Apple holds the highest average rating (5.22), followed by Nothing (5.15), Sony(5.00), and Oneplus (4.78).
Ø The P-value: The calculated P-value is 0.502396. Since this is significantly greater than the standard alpha level of 0.05, we fail to reject the null hypothesis.
Ø F-Statistic: The F-value (0.787745) is much smaller than the F-critical value (2.66), confirming that the variance between the brands is minimal compared to the variance within the groups.
6. Conclusion
The ANOVA test was conducted to examine whether there is a significant difference in consumer ratings among selected smartphone brands—OnePlus, Apple, Nothing, and Sony. Based on the ANOVA summary, the calculated F-value is 0.7877, which is less than the critical F-value of 2.6611. Additionally, the p-value (0.5024) is greater than the significance level of 0.05.
Since the calculated F-value does not exceed the critical value and the p-value is greater than 0.05, the null hypothesis is accepted. This indicates that there is no statistically significant difference in the mean consumer ratings of the selected smartphone brands. Therefore, it can be concluded that consumers rate these smartphone brands in a similar manner.
