Question

The class marks of a frequency distribution are 26,31,36,41,46,51, Find the true class limits.

Answer 1

The class frequency distribution are:-

$26 + 31 + 36 + 41 + 46 + 51 \\ divide \: by \: the \: no \: of \: frequency \: 6 \\ so \: the \: ans \: s \: 38.5$

Answer 2

Step-by-step explanation:

Given : The class marks of a frequency distribution are 26,31,36,41,46,51.

To find : The true class limits ?

Solution :

The limit range between class marks is given by,

$\frac{31-26}{2}=\frac{5}{2}=2.5$

So, the true class limits are

$23.5-28.5$

$28.5-33.5$

$33.5-38.5$

$38.5-43.5$

$43.5-48.5$

$48.5-53.5$
