ms. gomez was looking at how many students are in each of her classes. find the median number of students.

Explanation:

Step1: Count total data points

There are 1 + 2+2 + 3+1=9 data - points.

Step2: Determine position of median

Since (n = 9) (an odd number), the median is the (\left(\frac{n + 1}{2}\right))-th value. (\frac{9+1}{2}=5) - th value.

Step3: Arrange data in ascending order and find median

The ordered data set: 20, 23, 23, 25, 25, 26, 26, 26, 28. The 5 - th value is 25.

Answer:

25
