The question tests the knowledge of the term Median.

Median represents middle value.

Here in this question, median value will be the one represented by the errors made by 50-51% employee.

Up to 3 errors, 41% of employees are done. Now then 4 errors are made by next 17% of the employees. They will represent our median value.

Hence median errors = 4
