Question

Find the mid point of the class interval 5-15​

Answer 1

Concept: Statics, collection and presentation of data,

Given that: Class interval 5to15,

Solution:

   We know that, If m is the Midpoint for a class then h is the class size,

then lower limit of the class interval= $(m-\frac{h}{2})$,

        upper limit of the class interval= $(m+\frac{h}{2})$,

we have given that class interval= 5to15

class size= 15-5

               =10,

so, class interval formed,

               →         $(m-\frac{h}{2})-(m+\frac{h}{2})$

               →         $(5-\frac{10}{2})-(5+\frac{10}{2})$

                    →     $(5-5)-(5+5),\\(0)-(10),\\10,$

Hence midpoint of the class interval is 10,

Final Answer: midpoint of the class interval is 10,
