Midpoints
Cumulative frequency
1. Construct a frequency distribution for the variable, Miles per Gallon (Highway) using a
c lass width of 3 and starting with the lowest value in the data set.
For example, if the lowest value in the data set is 9 and the class width required is 3, then
The classes should consist of 9–11, 12–14, etc.
2. Construct a frequency distribution for the variable, Annual Fuel Cost using 300 as the
Class width. Start with the category 1200-1499, 1500-1799, etc.
3. When buying a brand new car, what factors or variables do you take into consideration before making the purchase?
