Why are graphs important in statistics?
Graphs visualize data allowing the brain to interpret a large data set quickly and infer trends.
Why is graphs important?
IT helps visualizes data, putting it in perspective and comparison.
What is the purpose of using graphs?
to interpret, and analyse data. to be able to see it clearly, with graphs you can find out important facts about the data you collected and use what you know to improve or change something.
What are 2 graphs that compare 2 sets of data?
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.
All graphs must have what?
Some data.
