Average age of the population calculated as the arithmetic mean.
Another parameter determining the average age of the population is the median age.
What does standard deviation of age mean?
In general, the standard deviation tells us how far from the average the rest of the numbers tend to be, and it will have the same units as the numbers themselves.
If, for example, the group {0, 6, 8, 14} is the ages of a group of four brothers in years, the average is 7 years and the standard deviation is 5 years.
How do you find the mean age?
To find the mean add all the ages together and divide by the total number of children.
