Final answer:
The data obtained from UPC codes at a check-out counter is nominal, which is a type of categorical data. The number of times per week is quantitative discrete, duration is quantitative continuous, and house colors are qualitative data.
Step-by-step explanation:
The type of data obtained from UPC codes at a check-out counter is D) Nominal data. UPC codes are unique identifiers for products and represent a form of categorical data. When the checkout scanner reads a UPC code, the associated information typically includes the product name, size, and price. However, UPC codes themselves do not contain quantitative information about the number of products sold or the sale price; they merely serve as a reference to look up that information in the store's database.
Answering the question about the type of data in this survey, based on the examples provided:
- Number of times per week is quantitative discrete data because it counts the instances which are whole numbers.
- Duration (amount of time) is quantitative continuous data because time can be measured with precision beyond just whole numbers.
- Colors of houses would be considered qualitative or categorical data because colors are descriptive and do not have a numerical value.
