## Calculate the Average (Mean), Sample Standard Deviation, and 95% Confidence Interval

If you want to enter numbers with magnitudes that are either very large or very small,

then you can enter them using scientific notation. But you will have to enter them a certain way.

For example, 1.254 x 10^{-8} would be entered as 1.254e-8.

The results are not reported with the appropriate number of digits. You'll need to report them correctly.
