Question

Draw frequency distribution table for the following data :

$14,18,14,17,15,15,17,15,14,14,19,17,20,20,15,16,17,18,18,16$,

$20,16,16,16,17,19,14,20,14,18,17,15,14,17,16,17,16,15,20$.

Answer 1

Drawing frequency distribution table -

Given data,

$14,18,14,17,15,15,17,15,14,14,19,17,20,20,15,16,17,18,18,16$, $20,16,16,16,17,19,14,20,14,18,17,15,14,17,16,17,16,15,20$

We will make frequency table by using tally marks.

Tally marks are the representation of the data in the form of vertical lines. We put one vertical line (|) for each of the four counts. A diagonal line (\) is put for the fifth count. These marks are tally marks.

Hence, distribution table for the given data given as-

Number	Tally Marks	Frequency
14		7
15		6
16		7
17		8
18		4
19		2
20		5
	Total	39
