Standard Deviation in Excel Help?

What do I input into standard deviation aka what's number 1 and whats number 2?

I am examining the health of various populations and in each column from a-x I have the population total, number of hiv/aids infection, diabetes, etc. I have already calculated the mean under each disease/population column.

My professor said he wants to know the standard deviation, but I have no idea what it is!

Help, definition, assistance! Thanks!

Standard Deviation is the measure of how uniform, or dispersed your data points are, probably assuming a normal distribution (bell curve).

In Microsoft Excel the standard deviation is computed from STDEV( list of values ). For example, if you want the standard deviation for the values in rows 3 - 30 of column C, type

=STDEV(C3:C30)

in the cell you want to see that value

For the mean you used "=average(b1,b2,b3...)" for standard deviation use "=stdev(....)" of the same cells. Look under "Insert, Function" on the tool bar in Excel.
