Question

What is the class mark and class interval for 5 to 10 class interval

Answer 1

The class interval = 5 - 10 and the class mark = 7.5

Step-by-step explanation:

We have,

Class interval for 5 to 10

To find, the class mark and class interval for 5 to 10 = ?

∴ Class interval for 5 to 10

Class interval = 5 - 10

Here, lower limit = 5 and upper limit = 10

We know that,

The class mark = $\dfrac{Lower limit+Upper limit}{2}$

$=\dfrac{5+10}{2}$

$=\dfrac{15}{2}$

= 7.5

Thus, the class interval = 5 - 10 and the class mark = 7.5

Answer 2

lower limit+ upper limit/2

=5+10/2

=15/2

=7.5
