What graph is best for relative frequency?
Relative- frequency histograms are better than frequency histograms for comparing two data sets. The same vertical scale is used for all relative-frequency histograms — a minimum of 0 and a maximum of 1 — making direct comparison easy.
How do I change frequency in Minitab?
To use frequency columns when you create a graph, click Data Options. On the Frequency tab, enter the column or columns that contain the frequency data. You can designate a different frequency column for each graph variable that you enter on the main dialog box.
How do you plot a graph on Minitab?

What is relative frequency bar graph?
A relative frequency bar graph looks just like a frequency bar graph except that the units on the vertical axis are expressed as percentages. In the raisin example, the height of each bar is the relative frequency of the corresponding raisin count, expressed as a percentage: See Note 9, below.
How do I find relative frequency?
A relative frequency is the ratio (fraction or proportion) of the number of times a value of the data occurs in the set of all outcomes to the total number of outcomes. To find the relative frequencies, divide each frequency by the total number of students in the sample–in this case, 20.
