The following table gives the frequencies of most commonly used letters a, e, i, o, r, t, u from a page of a book :
Letters a e i o r t u
Frequency 75 125 80 70 80 95 75
Represent the information above by a bar graph.
Solution:
Given, the table represents the frequencies of most commonly used letters a, e, i, o, r, t, u from a page of a book.
We have to represent the information by a bar graph.
We can represent the frequencies of most commonly used letters on the horizontal axis choosing any scale.
Let one head be represented by one unit.
We can represent the expenditure on the vertical axis.
Since, the maximum frequency is 125
Let the scale be 1 unit = 15
Consider first head i.e., letter a
Frequency = 75
Since 1 unit = 15
5 units = 75
We draw a rectangular bar with width 1 unit and height 5 units.
Similarly, other heads are drawn by leaving a gap of 1/2 unit in between two consecutive bars.
The bar graph for given data is shown below,
