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!
