Q: Why bar graphs are useful for comparing data?

Write your answer...

so you know the relationship between the 2 variables

data of what u want

double bar graphs are used for comparing data between 2 different things.

bar graphs are for measuring points of data.

Bar graphs show an '''amount''' of data. Line graphs show data '''over time.''' Pie graphs show a '''percentage''' in the data.

Bar graphs are used to display grouped data

bar graphs aid geographical understanding as they enable simple comparisons to be made and can be used to display a variety of data such as populations. Also there are many different types of bar graphs that can display different types of data. For example a compound could be used to show the populations in different countries in different years. Divergent bar graphs can also show positive and negative data.

Bar graphs are usually used for comparing. You could go into more detail, but that's the gist of it..

bar graphs use categorical data

Comparison :)

Statistics involve the comparing of sets of data and can be in the form of line graphs, pictograms, bar charts or pie charts

line graphs, bar graphs,and circle

Both bar graphs and picture graphs show statistics (data) in a visual (graphic) form.

Actually, they are useful. At least in some cases.

Bar graphs can compare two sets of data, as well as line graphs and circle graphs. To better improve my answer, double line graphs and double bar graphs compare two sets of data. Circle graphs cannot however, because they compare parts of a whole instead of, as a bar graph would, the amount of something. A circle graph is also incapable of showing data growth over a period of time, as line graphs do. All in all, circle graphs cannot compare to sets of data, and bar graphs and line graphs must be doubled to do so.

bar graphs are simply used like any other graphs just to figure out any kind of data.

like its a bar graphs

sometimes they can

Circle graphs show data in a circle, while line graphs are akin to join the dots, and a bar graph shows data in vertical or horizontal bars, but all three show the same data results.

comparisons

if you are graphing a change over time, a line graph. if you are comparing data, it's a bar graph.

You can use pie charts, line graphs, bar graphs and scatter point graphs to present data.

They both show a set of data. Line graphs show data over time. Pie graphs show percentages in data.

to show the result of data

They can both show the same data. You can use quantitative or categorical data with both of them.
