# Frequency Table

How to make and solve a frequency table: 2 examples and their solutions.

## Example

Make a table like this.

Name the columns

Interval, Tally, and Frequency.

It says

use 5 intervals starting from 50-59.

So write the intervals

50-59, 60-69, 70-79, 80-89, and 90-99.

Find the values in 50-59.

There are,

56 and 52

two values.

So draw two tallies

in the Tally column.

And write 2

in the Frequency column.

While counting the values,

mark the values like this.

Find the values in 60-69.

There are,

60, 69, and 67,

three values.

So draw three tallies

in the Tally column.

And write 3

in the Frequency column.

While counting,

mark the values like this.

Find the values in 70-79.

There are,

74, 78, 77, 75, 70, 74, and 74,

seven values.

So draw seven tallies

in the Tally column.

And write 7

in the Frequency column.

Find the values in 80-89.

There are,

81, 81, 85, 84, 80, and 88,

six values.

So draw six tallies

in the Tally column.

And write 6

in the Frequency column.

The remaining values are the values in 90-99.

There are,

91 and 97,

two values.

So draw two tallies

in the Tally column.

And write 2

in the Frequency column.

So this is the frequency table

of the given data.

## Example

The values less than 80 are

in these three intervals:

50-59, 60-69, and 70-79.

So the number of these values is,

add the frequencies of these intervals,

2 + 3 + 7.

2 + 3 = 5

5 + 7 = 12

So there are 12 values

that are less than 80.
