Question

How do I find class midpoints $?$

Answer 1

To find the class midpoint:

We can find the class midpoints of each class by adding the lower class limit and the upper class limit, then dividing by two:

$\mathbf{\text{Class midpoints=}}\frac{\mathbf{lower}\mathbf{}\mathbf{class}\mathbf{}\mathbf{limit}\mathbf{+}\mathbf{upper}\mathbf{}\mathbf{class}\mathbf{}\mathbf{limit}}{\mathbf{2}}$

For example, in class interval $0-10$:

Lower class limit is $0$ and the upper class limit is $10$.

Then, class midpoints will be:

$\frac{0+10}{2}=5$

Hence, the required answer is: Add the lower class limit and the upper class limit, then divide by $\mathbf{2}\mathbf{.}$
