If 10, 13, 15, 18, x + 1, x + 3, 30, 32, 35, 41 are ten observations in an ascending order with median 24, find the value of x.

By arranging the data in ascending order,


10, 13, 15, x + 1, x + 3, 30, 32, 35, 41


We have;


N = 10 (even number)


Median = 24 (given)


Median =


24


24


48 = 2x + 4


2x = 44


x = 22


Hence the value of x = 22
