Question

The median of the following observations given in order 16,18,20,24-x,2x,28, 30,32 is 24
Find the value of x.
​

Answer 1

Answer:

median =X

X=sum of all observations/number of observations

X=168-x

24 =168 -x

x=168-24=144

Answer 2

Answer:

since the no. of observation is even, then

median= ( (n/2)th term + (n/2 +1)th term)/2

median= ((8/2)th term +(8/2 +1)th term)/2

median= (4th term + 5th term)/2

median= (24-x+2x)/2

median= (24+x)/2

24= (24+x)/2 ( median = 24 )

48= 24+x

24=x
