Answer:
First of all, we need to arrange the data in an ascending order. Thus, the data is presented below as:
15, 35, 43, 46, 48, 49, 50, 55
N = 8
Since the number of items in the series is even, thus the following formula is used to calculate the median.
Median=
Size of (
N
2
)th item + Size of (
N
2
+1)th item
2
=
Size of (
8
2
)th item + Size of (
8
2
+1)th item
2
=
Size of 4th item + Size of 5th item
2
=
46+48
2
=47
Thus, Median is 47.
