We created cumulative frequency histograms and relative frequency histograms today. For the cumulative frequency histograms, find the cumulative sum up to and including each line of the frequency table, for instance,
x freq cumulative freq
1-5 4 4
5-10 5 9
11-15 6 15
For the relative frequency distribution, divide the count for an interval by the total number of observations, n. What do you observe about the graphs of frequency and relative frequency????
