A researcher took a random sample of 65 individuals across the country to investigate the relation between hours worked per week and income earned per year. For each individual, the hours worked per week and yearly income (measured in ?000?s dollars) were recorded. The data are stored in HOURSWORKED65 worksheet. In addition to the variables of hours worked and income earned, the individuals were also asked to respond to survey questions concerning other variables (e.g. occupation, location, etc). First, the researcher categorised the data into six occupation groups and six location groups and calculated the frequencies as presented in the tables below.

Which graphical technique or chart should be used if the researcher is interested in comparing the number of individuals in each occupation group??
