Identify the level of measurement of the data, and explain what is wrong with the given calculation. In a survey, the of respondents are identified as for for for and for anything else. The average (mean) is calculated for respondents and the result is hair colors 1 brown hair, 2 blond hair, 3 black hair, 4 567 1.5. The data are at the (1) level of measurement. What is wrong with the given calculation? A. The true average (mean) is 2.1. B. Such data are not counts or measures of anything, so it makes no sense to compute their average (mean). C. Such data are not counts or measures of anything, so the average (mean) needs to be computed in a different way. D. There is nothing wrong with the given calculation.
