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. Here, the data consists of survey responses about participants' favorite menu item, which are categories (e.g., burger, salad, pizza) rather than numbers.
Step 3: Since the data is categorical, classify it as qualitative data.
Step 4: Determine the level of measurement for qualitative data. The levels are nominal and ordinal. Nominal data are categories without any inherent order, while ordinal data have a meaningful order or ranking.
Step 5: Because favorite menu items are categories without any ranking or order, the appropriate level of measurement is nominal.
