Question

the data are at the nominal level of measurement. what is wrong with the given calculation? a. such data are not counts or measures of anything, so the average (mean) needs to be computed in a different way. b. the true average (mean) is 2.1. c. such data are not counts or measures of anything, so it makes no sense to compute their average (mean). d. there is nothing wrong with the given calculation.

Explanation:

Nominal - level data consists of categories or labels. They do not have a numerical value that can be meaningfully averaged. For example, if we have nominal - level data like "colors (red, blue, green)", calculating a mean for these labels is not appropriate as they are not counts or measurements on a numerical scale.

Answer:

C. Such data are not counts or measures of anything, so it makes no sense to compute their average (mean).
