The standard deviation is approximately 1/4 the range; therefore, determine the difference between the highest and lowest value in each data set, then divide by 4. This is a rough estimate, but if you actually calculate the standard deviation and it's way off the estimate, then you may need to redo your calculations.

I hope this will help get you started.
