To calculate the mean, we sum up all the scores and divide it by the total number of students. Let's calculate it:
Sum of scores = 60 + 51 + 50 + 57 + 73 + 47 + 56 + 52 + 51 + 59 + 58 + 53 + 48 + 48 + 58 + 60 + 57 + 58 + 49 + 53 = 1120
Total number of students = 20
Mean = Sum of scores / Total number of students
= 1120 / 20
= 56
Therefore, the mean score for the given 20 students in math 7 is 56.
