Question

Median 30,25,32,23,42,36,40,33,21,43

Answer 1

Hey Friend ☺

☆ STATASTICS ☆

To Find median arrange the given data in ascending order.

Ascending order = 21 , 23 , 25 , 30 , 32 , 33 , 36 , 40 , 42 , 43

N is the number of observations

N = 10

N/2 = 10/2 = 5 th observation

N + 2/2 = 12/2 = 6 th observation

Median = 5th observation + 6th observation/2

= 32 + 33/2

= 65/2

= 32.5

So the median is 32.5

Hope it helps you ..!!

Answer 2

first we arrange in ascending order the given number
21, 23, 25, 30, 32, 33, 36, 40 , 42, 43
then count the no.
n=10
median = for even no. of term
median =( n/2) term + (n/2+1) term
= 10/2+10/2+1
5+ 6 the term/2
is median
65/2
32.5 is ans
