Q1. Defect counts per crate were 0, 1, 2, 3, 4 and 55. Which central measure drops most sharply when the value 55 is removed from the calculation?
Answer: Mean
Explanation: Removing the outlier 55 barely shifts the median (still around 2.5) but dramatically cuts the mean from 10.83 to 2, making the mean the most sensitive measure.
