A data set about injuries and illnesses at a company lists values of incidents per month. Element 469 of the data set is 2.7 incidents per month. The units the variance of this data set be stated is incident-squared.

Explanation:

The units of the variance, which is the average squared deviation, are those of the data squared, although units may not be intuitively, or make sense physically (interpretable) and makes it difficult to get a direct relation between the variance with the data indicators.
