Frequency vs. Relative Frequency Histograms
- Tim Brzezinski
Change the frequency histogram by moving the LARGE POINTS up and down. Note how the percent frequency histogram changes on the right.
Suppose each of the bars on the left have the same height (just make sure these heights are greater than zero). What is the value of each percent frequency bar on the right? Why is this?
Why is it that when we increase the height of one bar on the left, the heights of the other bars in the percent frequency histogram (on the right) go down?
What is the highest possible value any one bar in the percent frequency histogram can reach? Under what circumstance(s) does this occur?
