Answer
Step-by-step explanation:
Answer
(i) Let us arrange the numbers in ascending order as below.
7,14,15,21,22,23,24
Number of items n=7
Median =(
2
n+1
)
th
observation (∵n is odd)
=(
2
7+1
)
th
observation
=4
th
observation =21
(ii) Let us arrange the numbers in ascending order
7,9,10,12,13,15,17,21,32,42.
Number of items n=10
Median is the mean of (
2
n
)
th
and (
2
n
+1)
th
observations. (∵n is even)
(
2
n
)
th
observation =(
2
10
)
th
observation =5
th
observation =13
(
2
n
+1)
th
observation =6
th
observation =15.
∴ Median =
2
13+15
=14
