Question

Find the median of he following data 41,43, 127, 99, 61, 92, 71, 58, 57, . If 58 is replaced by 85, find the new median.

Answer 1

Answer:

First arrange the given observations in ascending order as below

41, 43, 57, 58, 61, 71, 92, 99, 127

Now the number of observations = 9 which is odd

So

Median

= 5th term

= 61

Now if 58 is replaced by 85

Then the observations are

41, 43, 57, 61, 71,85, 92, 99, 127

Now the number of observations = 9 which is odd

So

Median

= 5th term

= 71
