Darren Pollard · Answer 2

The mean of a dataset is the all members of the dataset added together and then divided by the number of members in the set. From your description of the number line, I've created a list of members.

16, 17, 17, 17, 17, 19, 19, 19, 19, 21, 22, 22, 23, 25

Adding all members of this set up produces the value 273. There are 14 members in the set, so 273 / 14 = 19.5. Thus, the mean of the set is 19.5
