To calculate it, you need to find out the simple average of the numbers first. I want to be able to input a variable amount of data and output the average and standard deviation.

It is represented by the Greek letter '?'.

Here are some methods on how to find standard deviation. However, all you need to do to understand the key concept is to see a basic example you can easily work out by hand. Statistical tests such as the t -test intrinsically depend on the concept of a standard deviation. Tutorial on calculating the standard deviation and variance for statistics class. Unless I misunderstood your problem, I see no way you can calculate this number without knowing a standard deviation.
Now, hope you know how to calculate this value, and complete your works without too much hassle. This piece of information enlists a couple of methods of how to find standard deviation.
