Question
Calculate the median of following data:
145, 130, 200, 210, 198, 234, 159, 160, 178, 257, 260, 300, 345, 360 and 390.
Solution
By arranging data we get the following data:
130, 145, 159, 160, 178, 198, 200, 210, 234.1 257, 260, 300, 345, 360 and 390.
Median = Value of N + 1 item
2
= 15 + 1
2
= Value of 8th item
Value if 8th item = 210
