Question

If the median of the distribution given below is 28.5, find the values of X and y
C.I.= 0-10, 10-20, 20-30, 30-40, 40-50, 50-60
F= 5, 8, x, 15, y, 5
total=60

Answer 1

Answer:

SOLUTION IS IN THE ATTACHMENT

Median:

Median is that value of the given observation which divides it into exactly two parts.

MEDIAN for the GROUPED data :

For this we find the Cumulative frequency(cf) of all the classes and n/2 , where n =  number of observations.

Now find the class whose Cumulative frequency is greater than and nearest to n/2 and this class is called median class,then use  the following formula calculating the median.

MEDIAN = l + [(n/2 - cf )/f ] ×h

Where,

l = lower limit of the median class

n = number of observations

cf = cumulative frequency  of class interval preceed the  median class

f = frequency  of median class

h = class  size
