Question

Mean and median of following data
0,-2,2,-4,4

Answer 1

Answer:

Mean = Median = 0

Step-by-step explanation:

Arranging the terms in an ascending order,

-4, -2, 0, 2, 4

Mean = Sum of all terms / Number of terms

Mean = [  (-4) + (-2) + 0 + 2 + 4 ] / 5

Mean = [ -2 + 2 -4 + 4 ] / 5

Mean = 0/5

Mean = 0

When number of terms is odd, Median is the middle term.

Hence, median = 0
