- For a data-set, the standard deviation has the same unit as the data-set, both for the sample and the population.
- The variance has the unit squared, both for the sample and the population.
- For example, if the data-set is in metres, the standard deviation will be in metres while the variance will be in squared metres.
-----------------------------
In this question, the data-set is in grams.
- The standard deviation, both for the sample and the population, in items a and b, will be in grams.
- The variance, both for the sample and the population, in items c and d, will be in grams squared.
