I would say in America the mean IQ is about 60 and the standard deviation is about 15, this is about true for all ages.
Standard deviation can only be zero if all the data points in your set are equal. If all data points are equal, there is no deviation. For example, if all the participants in a survey coincidentally were all 30 years old, then the value of age would be 30 with no deviation. Thus, there would also be no standard deviation.A data set of one point (small sample) will always have a standard deviation of zero, because the one value doesn't deviate from itself at all.!

"Risk probability" does not quite make sense, perhaps you mean just how to calculate risk. There are many formulas and methods, a lot of them highly complex mathematical models. Risk calculation is an important subset of portfolio theory. For the simplest cases, consider some of the following definitions: * the greatest dive that a stock took over a given historical time period. For example, if stock A dropped 30% maximum over past 5 years before rebounding, and stock B dropped 40% maximum over the same period - then by this metric you can see that stock B is riskier. * standard deviation of the returns over a historical time period. Take as your data set the prices a stock assumed over the last 5 years daily. You can calculate the standard deviation of this data set. The standard deviation is a measure of risk.
You would have about 1/2 of 1 % chance of living to 100 since age 100 is three standard deviations (SD) from the mean. If you are with in three SD of the mean you have 99% of the data set or probablity contained. Hence, you would be missing 1% of which half would be above age 100 and half would be below (73-27) age 46.
The average age is 11 to 12 years of age. Standard deviation is 2 years.

Some secrets to picking a mutual fund include analyzing the risk (or standard deviation of the fund) as well as the return of the fund over 1 year, 3 years, 5 years, and 10 years intervals.
It is the sample mean age of 21.7.
