Answer:
16 ; 16.5
Step-by-step explanation:
Given the data:
X = 9, 20, 17, 21, 16, 13
1.) The mean of the data:
Σ(X) / n
n = sample size ; n = 6
(9 + 20 + 17 + 21 + 16 + 13) / 6
= 96 / 6
= 16
2.) The median :
Rearranged data : 9, 13, 16, 17, 20, 21
1/2 (n + 1)th term
1/2 (6 + 1)th term
1/2 (7) th term
The 3.5 th term is the median:
(3rd + 4th) / 2
(16 + 17) / 2
33 /2 = 16.5
