identify the level of measurement of the data, and explain what is wrong with the given calculation. in a set of data, alert levels are represented as 0 for low, 1 for medium, and 2 for high. the average (mean) of the 635 alert levels is 0.9. the data are at the level of measurement.

identify the level of measurement of the data, and explain what is wrong with the given calculation. in a set of data, alert levels are represented as 0 for low, 1 for medium, and 2 for high. the average (mean) of the 635 alert levels is 0.9. the data are at the level of measurement.

Answer

Brief Explanations:

The data are at the ordinal level of measurement. Ordinal data have an inherent order (low < medium < high here), but the differences between the values are not meaningful in a numerical - arithmetic sense. Calculating the mean is inappropriate for ordinal data as the numbers (0, 1, 2) are just labels for the order and not true numerical values for which arithmetic operations like finding the mean are valid.

Answer:

Ordinal; Calculating the mean is inappropriate for ordinal - level data as the numbers are just order - labels and not numerical values for arithmetic operations.
