Question

Sociologists argued that women on average earn less than men as women often choose to work less hours. They further suggest that the choice of hours worked may be driven by various factors such as age, childcare needs, occupation choice and flexibility. To investigate the relation between hours worked and income earned by Australian men and women, a researcher plans to survey a sample of individuals across the country.

First, the researcher categorised the data into six location groups and six occupation groups, and calculated the frequencies given below.

Frequency tables

Location		Occupation
Location category	Frequency	Occupation category	Frequency
Location group A	5	Occupation group 1	4
Location group B	7	Occupation group 2	26
Location group C	12	Occupation group 3	15
Location group D	25	Occupation group 4	12
Location group E	10	Occupation group 5	5
Location group F	6	Occupation group 6	3
