The mean is different from the mode and the median
I am reading a study in which the mean age of a population is 41 years. The mode and median are however both 35 years. I do not have access to the raw data. How I can interpret the difference between the mean and the mode/median?

Here is a very primitive example: imagine the dataset has only five entries:
34, 35, 35, 48, 53
The mode and median are 35 and the mean is 41. This basic histogram shows what you might expect: an overshoot of a small number of entries with ages that are much higher than the mode.

Do you have a similar question?
