Calculate the mean of your data set.
Subtract the mean from each of the data values and list the differences.
Square each of the differences from the previous step and make a list of the squares.
In other words, multiply each number by itself.
Be careful with negatives. A negative times a negative makes a positive.
Add the squares from the previous step together.
Subtract one from the number of data values you started with.
Divide the sum from step four by the number from step five.
Take the square root of the number from the previous step. This is the standard deviation.
You may need to use a basic calculator to find the square root.
Be sure to use significant figures when rounding your answer.

Aerospace Engineering specifically. :)

We covered some of it in Calculus, as a side-study while finals were going on. ( We don't have homework / studies during finals. )

Medium difficulty.

Geometry and calculus plays out to be more helpful than you think in it.
