Question:

The following table shows distributions of bachelor€™s degrees earned in 2005€“ 2006 for selected fields of study by all male graduates and by all female graduates.
(a) How many female psychology majors graduated in 2005€“ 2006?
(b) Since the total numbers of male and female graduates are fairly different€” 504,600 and 676,000€” it is helpful to convert first to relative frequencies before making comparisons between male and female graduates. Then, inspect these relative frequencies and note what appear to be the most conspicuous differences between male and female graduates.
(c) Would it be meaningful to cumulate the frequencies in either of these frequency distributions?
(d) Using just one graph, construct bar graphs for all male graduates and for all female graduates.
