Answer 2

Answer:

Mean: 17.55

Median: 19

Step-by-step explanation:

Given scores = 14, 25, 17, 22, 20, 19, 10, 8, 23

No. of scores = 9

Mean = Sum of Given Scores / No. of scores = (14+25+17+22+20+19+10+8+23)/9 = 158/9 = 17.55

Median is the middle value. To find the median, first arrange the data in either ascending or descending order. Here, I'll arrange the data in ascending order.

8, 10, 14, 17, 19, 20, 22, 23, 25

No. of terms (n) = 9

This means that n is odd. If n is odd, then median = (n+1)/2 th term = (9+1)/2 th term = 10/2 th term = 5 th term = 19. Hence 19 is the median.
