Step 1: Understand the difference between quantitative and qualitative data. Quantitative data represents numerical values that can be measured or counted, while qualitative data represents categories or characteristics that describe attributes or qualities.
Step 2: Identify the nature of the data in the problem. Survey responses about participants' favorite menu item are categories (e.g., burger, salad, pizza), so this data is qualitative because it describes a characteristic rather than a numerical measurement.
Step 3: Review the levels of measurement for qualitative data: Nominal and Ordinal. Nominal data categorizes without any order (e.g., types of menu items), while Ordinal data categorizes with a meaningful order or ranking (e.g., satisfaction ratings).
Step 4: Determine which level applies. Since favorite menu items are categories without any inherent order or ranking, the appropriate level of measurement is Nominal.
Step 5: Conclude that the data is qualitative and measured at the nominal level.
