Question

Find the median for the following distribution table.
CI. | 1-3 | 3-5 | 5-7 | 7-9 | 9-11.
7 | 8 | 2 | 2 | 1
For the following given table change the distribution to a less than type
C.I. 50-55 | 55-60 160-65 | 65-70 | 70-75 | 75-80 |
_f | 2 | 8 | 12 | 24 | 38 | 16​

Answer 1

Answer:

sum of f = 100

than ,

MD = N/2

= 50 term

so, md lies in 70 - 75

according to formula,

MD = l + (n/2 - cf)/ f * h

where ,

l= 70

n/ 2 = 50

cf= 46

f = 38

Now, putting on formula

70 + ( 50 - 46 ) / 38 * 5

Now, solve this in BODMAS rule ,
