What is the importance of bar graph?

Answer 1

Like all graphs , bar graphs give a visual representation of numerical data. This representation is designed to make it easier to understand the data it presents.

It may also highlight the specific relevant features of the data. Bar graphs make it easy

to compare the relative size of quantities, particular if the reader is more adept at judging the relative heights of bars than he is at mental arithmetic. scaling a bar graph can be used for two reasons, to jump past a large group of numbers unused (say the bar graph goes from 1-1000 but none of the data starts below 500)

Scaling can be important to emphasize a difference in numbers too, suppose item a is at 700, item b is at 850, and item c is at 1000. if your bar graph jumps from 1 to 500 and then goes up in increments of 100, it can make 700 look like its far less than 850 or 1000. this is usually a business tactic done to impress board members when presenting lackluster numbers.
