Question

if the classmark is 5 and class width is 10 then find classes ?

Answer 1

Answer :

Class ( 0 - 10 )

Explanation :

Given class mark (xi) = 5

class width (h) = 10

class = ( xi - h/2 , xi + h/2 )

= ( 5 - 10/2 , 5 + 10/2 )

= ( 5 - 5 , 5 + 5 )

= ( 0 , 10 )

Therefore ,

class interval ( 0 - 10 )
