1. Identify the type of data (qualitative/quantitative) and the level of measurement for the temperatures in Fahrenheit in which the respondents to a survey live. Explain your choice.

Are the data qualitative or quantitative?

A. Quantitative, because descriptive terms are used to measure or classify the data.

B. Qualitative, because descriptive terms are used to measure or classify the data.

C. Quantitative, because numerical values are used to measure or classify the data.

D. Qualitative, because numerical values, found by either measuring or counting, are used to describe data.

What is the data set's level of measurement?

A. Ordinal, because the data are categories or labels that can be ranked.

B. Ratio, because the differences in the data can be meaningfully measured, and the data have a true zero point.

C. Interval, because the differences in the data can be meaningfully measured, but the data do not have a true zero point.

D. Nominal, because the data are categories or labels that cannot be ranked.
