Question 2
Two statistics students are arguing over which type of bar graph to use. One insists that a bar graph that displays the relative frequency will be better for displaying the overall shape of the data. The other holds that only a frequency bar graph will suffice. You happen along and hear their conversation. What advice do you give them?
◦
The relative frequency bar graph is superior at displaying the overall shape of the data.
◦
The frequency bar graph is superior at displaying the overall shape of the data.
