Final answer:
In the study, the prices of fruit salad are quantitative data, because they are numerical and measurable, while types and varieties of fruit salad are qualitative data, as they describe non-numeric characteristics.
Step-by-step explanation:
In the given study, the prices of fruit salad represent quantitative data. This is because prices are numerical and can be measured on a continuous scale. In contrast, favorite type of fruit salad, types of fruit in a fruit salad, and varieties of fruit salad are examples of qualitative data, which include categories or descriptions of attributes that are not numerical.
For further clarity, quantitative data is anything that can be counted or measured and can be either discrete (counted in whole numbers) or continuous (measured and can include fractions or decimals). Examples include the number of fruit salads sold (discrete) or their weights (continuous). Qualitative data includes categories or descriptors that do not have a numerical value, as in the types or varieties of fruit salad.
