Question

Maximum frequency of a data is $2000$. A bar graph is to be drawn for this data. What would be appropriate scale if it is desired that the longest bar is around $10cm$ tall?

Answer 1

Finding the scale of the graph

Given that,

Maximum frequency $=$$2000$

Longest bar of the data $=$$10cm$

Now clearly

Longest bar of the data $=$Maximum frequency of the data

$\Rightarrow$ $10cm$ $=$$2000$

$\Rightarrow$ $1cm$ $=$$\frac{2000}{10}$

$=200$

Therefore, the appropriate scale for the bar graph is $1cm$$=200units$
