Answer 2

Answer:

Concept:

When the total number of observations is given, the Sturges rule is used to determine the number of classes.

Step-by-step explanation:

Given:

Number of workers in a factory = 256

Find:

Number of classes

Solution:

We simply need to recall the Sturges rule formula and then enter the number of classes and total frequency into the Sturges rule.

$\left\lceil\log _{2} n+1\right\rceil$

Here, n = Number of workers

By substituting the value in the rule,

$\left\lceil\log _{2} 256+1\right\rceil$

= 8 + 1

= 9.

Hence, the number of classes will be 9.
