can anyone help me to figure out how to work out STANDARD DEVEATION CALCULATIONS please?

Do you have a specific example? There are formulas for standard deviation you can use if you are expected to do the calculations by hand. You can also use calculators or statistical software packages. These are easier ways to achieve the same results.
