Question 8
The following table gives the frequencies of most commonly used letters a, e, i, o, r, t, u, from a page of a book.
LettersaeiortuFrequency751258070809575
Represent the information above in a bar graph.
We draw the bar graph of this data in the following steps.
Step I - We represent the letters (variable) on the horizontal axis choosing any scale, as the width of the bar is not important. But for clarity, we take equal widths for all bars and maintain equal gaps is not in between them. Let one letter be represented by one unit.
Step II - We represent the letters on the vertical axis. Since, the maximum frequency is 125, we can choose the scale as 1 unit = 15 frequency
Step III - To represent our first letter i.e., we draw a rectangular bar with width 1 unit and height 5 units.
Step IV - Similarly, other heads are represented by leaving a gap of 12 unit in between two consecutive bars.
The bar graph for given data is shown below.
