9152PS2025095_Batting_Performance_Under_Pressure
This analysis compares batting performance under pressure and low-pressure situations using simulated scores and a permutation test. The observed mean difference in scores was tested against 1000 randomly generated permutations. Results showed that the observed difference is unlikely due to chance, indicating a statistically significant impact of pressure on performance (if p-value < 0.05).
