Comparison :)
bar graphs are useful for comparing data b/c you cn actually see what the difference is between them.
comparisons
data of what u want
Actually, they are useful. At least in some cases.
so you know the relationship between the 2 variables
bar graphs are for measuring points of data.
circle graphs add up to 100% , bar and line graphs don't
Bar graphs are useful for showing comparisons among discrete categories or groups. They visually represent the quantity or frequency of each category, making it easy to identify trends, patterns, and differences. Bar graphs are effective for illustrating data across various fields, such as sales figures, survey results, and population statistics. Their straightforward format allows for quick interpretation and analysis of the information presented.
well...not sure if you know this but bar graphs already ARE bar graphs, the good news is you don't have to transform them... so half your work is already done XD!
bar graphs are usually used for results that have a variable whose units are described in words and the other variable whose units are described in numbers such as the y axis, the vertical line, is the number of people and the x axis, the line going horizontal, is the colour of eyes. bar graphs are not useful for the y axis and x axis both units are in numbers. these are mainly used for line graphs
Both bar graphs and picture graphs show statistics (data) in a visual (graphic) form.
