If you use technology, there is no need for the relative frequencies or the angles. A third type of qualitative data graph is a Pareto chart, which is just a bar chart with the bars sorted with the highest frequencies on the left. A bar graph is a specific way of representing data using rectangular bars where the length of each bar is proportional to the value they represent. The bars represent frequencies of distinctive values of a variable or commonly the distinct values themselves. A listing of data is too hard to look at and analyze, so you need to summarize it. This is just the frequency divided by the total. Your email address will not be published. Relative frequency is just the percentage as a decimal. There are 360 degrees in a full circle.

There are several different types of graphs that can be used: bar chart, pie chart, and Pareto charts. The relative frequency graph and the frequency graph should look the same, except for the scaling on the frequency axis. 3.
