Write the class size and class limits in each of the following:
$104, 114, 124, 134, 144, 154$ and $164$
Given:
$104, 114, 124, 134, 144, 154$ and $164$
To do:
We have to write the class size and class limit.
Solution:
$104, 114, 124, 134, 144, 154$ and $164$.
Class size $= 114 - 104$
$= 10$
Class Mark | Lower class limit | Upper class limit | Class limit |
104 | $104-\frac{10}{2}=99$ | $104+\frac{10}{2}=109$ | $99-109$ |
114 | $114-\frac{10}{2}=109$ | $114+\frac{10}{2}=119$ | $109-119$ |
124 | $124-\frac{10}{2}=119$ | $124+\frac{10}{2}=129$ | $119-129$ |
134 | $134-\frac{10}{2}=129$ | $134+\frac{10}{2}=139$ | $129-139$ |
144 | $144-\frac{10}{2}=139$ | $144+\frac{10}{2}=149$ | $139-149$ |
154 | $154-\frac{10}{2}=149$ | $154+\frac{10}{2}=159$ | $149-159$ |
164 | $164-\frac{10}{2}=159$ | $164+\frac{10}{2}=169$ | $159-169$ |
