In a relative frequency distribution, what does each $relativefrequency$ represent?

If a frequency table of grades has $5$ classes, what does this mean about the data?

Which of the following is a primary benefit of using graphs of frequency distributions in statistics?

A data set has a minimum value of 16 and a maximum value of 71. Without constructing a table, find the class width if you organized this data into 7 classes. Write the lower and upper class limits.

min = 16; max = 71; 7 classes.
