Question

(4) Find the true class for the following data.1-9, 10 - 19​

Answer 1

The true class for the following data. 1-9, 10 - 19​ are 0.5 - 9.5 and 9.5 - 19.5.

Step-by-step explanation:

To find, the true class of the data: 1 – 9, 10 –19 =?

First we have to convert the exclusive method to inclusive method.

So for a class limit a – b in exclusive method it will become

$(a-\dfrac{h}{2}) -(b+\dfrac{h}{2})$

$h=\dfrac{Lower limit of the class}{Upper limit of previous class}$

∴ The true class limit of the given data are shown in the table

Class      True class

1 - 9         0.5 - 9.5

10 - 19     9.5 - 19.5

The true class for the following data. 1-9, 10 - 19​ are 0.5 - 9.5 and 9.5 - 19.5.

Hence, the true class for the following data. 1-9, 10 - 19​ are 0.5 - 9.5 and 9.5 - 19.5.
