Introduction:
Cricket is a popular sport where player performance is closely analyzed by fans and experts. Evaluating players helps in understanding their consistency and overall contribution to the team. This study examines the performance of four players — Virat Kohli, Abhishek Sharma, Rohit Sharma, and Arjun Tendulkar — using statistical methods. One-Way ANOVA is applied to determine whether there is a significant difference in their average performance.
Objective:
To analyze and compare the performance of four players using One-Way ANOVA and determine whether there is a statistically significant difference in their mean performance.

Statistical Methods in Performance Analysis
Fisher (1925) introduced Analysis of Variance (ANOVA) as a powerful statistical technique to compare the means of multiple groups. It helps in identifying whether differences between groups are statistically significant or occur due to random variation. ANOVA has become one of the most widely used tools in performance analysis across various fields, including sports.
Application of ANOVA in Performance Comparison
Gupta and Kapoor (2014) explained that ANOVA is commonly used in research and business to compare group performance and measure variability. In sports analytics, it helps evaluate consistency among players by analyzing differences in their average scores and variations. The study highlights that players with lower variance tend to be more consistent, while higher variance indicates fluctuating performance.
Data Collection:
The data for this study was collected from secondary sources based on the performance records of players. The dataset includes performance scores of four players — Virat Kohli, Abhishek Sharma, Rohit Sharma, and Arjun Tendulkar. Each player has 33 observations representing their performance in different matches. The data is arranged in a tabular format and used for statistical analysis. One-Way ANOVA is applied to the collected data to compare the performance of players.
Data Analysis:
Equation:
F = Variance Between Groups / Variance Within Groups
Values:
F = 36.968 P-value = 2.82E-17 F crit = 2.675
Description:
The ANOVA results show that the F value is 36.968 and the P-value is 2.82E-17, which is less than 0.05. This indicates that the model is statistically significant. Since the P-value is less than 0.05, the null hypothesis is rejected. Therefore, there is a significant difference in the average performance of the players.
Conclusion:
As calculated, F (36.96838) is more than F crit (2.675387). Accept H₁, meaning any one of them is different.
