Is it true that the median is always one of the data points in a set of data?
No, it is not necessarily true that the median is always one of the data points in a set of data. The median is found by arranging the data in numerical order and selecting the middle value. This value might be one of the data points, but it could also be the average of two data points if there is an even number of values in the set.

What is the sum of all deviations of a data value from a measure of central location that will always be zero?
Difference (deviation) from the mean.
