Q. What makes a bar graph accurate?
You use a bar chart to compare the values of several numbers at once. The human brain is much better at assessing distance than it is area and angle, so people perceive bar charts more accurately than they do pie charts. Calculating the actual value of each group on a bar chart is also easier than on a pie chart.
