A company that produces software for managing investments is interested in the relationship between gender and the type of investment portfolios that self-managed investors hold. To find about this relationship, the company commissions a survey of 1200 self-managed investors. The contingency table lists the frequency counts for each category and for subtotals and totals. In this way it breaks down investors by their gender and by the predominant type of investment portfolio they have held over the past 12 months. Investors could nominate one type of portfolio only, so the outcomes relating to type of portfolio are mutually exclusive.
