Graphs being pictorial representations enable us analyse the data more methodically and easily. It is a much more user friendly way of presenting and analyzing data. Data are just raw and unprocessed information. And when they are charted out and categorized their numerical representations often confuse us when presented in tables. Compared to such representation of data, grapghs and pie diagrams aid us more efficiently.
graph can reveal patterns or trend that words and date tables cannot -from derek
patterns trends that words and data tables can not
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.
Yes, that is the purpose of a graph. It gives you a visual representation of data and you can see how it changed over time.
Visual tendancy of a set 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 use categorical data
line graphs are usually the most best way to present data. sometimes i use pie graphs or bar graphs, but usually line graphs are the most meaningful.
Graphs visualize data allowing the brain to interpret a large data set quickly and infer trends.
They both show a set of data. Line graphs show data over time. Pie graphs show percentages in data.
line graphs, bar graphs,and circle
bar graphs are for measuring points of data.
