Question

find the median for the following :



​

Answer 1

Answer:

2.10

Step-by-step explanation:

1.firstly write the cf of given equation.

2.Then apply the formula =l+(cf-n/2)×h

f

3.put the value in formula n/2=140 it's half of total frequency.

4.l= 10

Cf=182

f=133

H=5

5.Now solve it =10+(___182-140__)×5

133

6.10+(-58)×5

133

7.-280

133

8.2.10answer

Answer 2

Answer:

use formula l+[(n/2-CF)/F]×H

where l is lower limit of class interval

n is no. of terms

CF is cumulative frequency of class interval preceding the selected class interval

F is the frequency of the selected class interval

and H is the height

here, l is 25, n is 9, CF is 260 f is 6 and h is 5

putting allvalues in formula

median = 237.916
