Which measure of central tendency best describes this situation: the numbers of apples in 2-lb bags?
katrin [286]

Which measure of central tendency best describes this situation:

The number of apples in 2-lb bags?

Solution: The best measure of central tendency to describe the numbers of apples in 2-lb bags is mean. Because the variable under consideration is numeric and probably we would not see outliers in 2-lb bags.

Mean is the defined as the sum of observations divided by the number of observation. The mean takes into account all the observation of the data. Mean is most preferable when the data is numeric and there are no outliers in the data.

Therefore, in the given situation, where we have number of apples in 2-lb bags, the mean will be best to use.
