Q
You can compare two different data sets on the same chart.
A scatter graph.
The line and the bar graph is used to describe a graph that compares two sets of data.
The graph is called the 'line of best fit'
double line graph
I suggest a scatter-graph of line graph, with time as the independent axis.
When you are talking about data that is not continous. When you are talking about data that is not continous.
when a sets of data can be separated by 2 orders of variables, which are the independent & dependent variables.
To compare any two sets of data !
The advantage is that you can compare multiple data sets in the same chart
You can compare two different data sets on the same chart.
You can compare two different data sets on the same chart.
A double line graph is used to compare two sets of data. Usually the data is taken over a period of time and compared at set intervals.
They are used for when each data group contains two different sets of frequency data. A double bar graph is used to compare both between and within data groups
A scatter graph.
bar graph
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.
