1. Problem Description

The problem asks to find the median of the number of computers in classrooms based on the given data: Mrs. Jansen (4), Mrs. Rossi (3), Mr. Schmidt (4), Ms. Rojas (5), Miss Murphy (4), Mr. Watson (4), and Ms. Cohen (7).

2. Solution Steps

7. Sorting these numbers gives us: 3, 4, 4, 4, 4, 5,

7.

The median is the middle value in the sorted list. Since there are 7 numbers in the list, the middle number is the (7+1)/2 = 4th number.

The 4th number in the sorted list 3, 4, 4, 4, 4, 5, 7 is

4.
