Assume that the first set of scores above represents the IQ scores of children who have been participating in a school lunch program and the second set of scores represent the IQs of a similar group of children who have not participated in the program. Prepare appropriate graphical representations of the frequency and relative frequency distributions. Compare the two distributions by placing them on the same graph. Be sure to have equivalent intervals, if grouped. Why did you decide to compare frequencies, or relative frequencies? Assume that the third set above are data from a survey of riders of a city bus system.Each rider was asked to indicate the number of times he or she had taken a bus on a Sunday during the previous month. Prepare a graphical representation of the relative frequency data.
