Questions: Identify the data set's level of measurement. 7) list of zip codes for Chicago 8) number of pages in your statistics book 9) temperatures of 73 selected refrigerators 10) manuscripts rated "acceptable" or "unacceptable"

Solution Steps

To identify the level of measurement for each data set, we need to determine whether the data is nominal, ordinal, interval, or ratio.

7. Zip codes are nominal because they are labels used for identification and do not have a meaningful order.
8. Number of pages is a ratio because it has a true zero and the differences between values are meaningful.
9. Temperatures are interval because they have meaningful differences but no true zero.
10. Manuscript ratings are ordinal because they have a meaningful order but the differences between values are not necessarily consistent.

Zip codes are used as labels for identification purposes and do not have a meaningful order. Therefore, the level of measurement for zip codes is nominal.

The number of pages in a book has a true zero point and the differences between values are meaningful. This makes the level of measurement for the number of pages a ratio.

Temperatures have meaningful differences between values but do not have a true zero point. Thus, the level of measurement for temperatures is interval.

Manuscript ratings such as "acceptable" or "unacceptable" have a meaningful order but the differences between values are not necessarily consistent. Therefore, the level of measurement for manuscript ratings is ordinal.
