I would like to measure the relationship between smoking status and gender in a large sample size? What is the most appropriate type of graph?
Select one:
A. I should use a histogram, because I have a large sample size
B. I should use a cluster bar graph, and report the percentage values on each bar
C. I should use a pie chart, because I can report the number of males vs females that smoke or don't smoke.
D. I should use a frequency table, because I can work out the cumulative and relative frequency values.
