Formulae for the standard deviation. Whilst it is not necessary to learn the formula for calculating the standard deviation, there may be times when you wish to include it in a report or dissertation. The standard deviation of an entire population is known as Ï (sigma) and is calculated using:

The maggot gorges itself with food until it is ready to enter the pupal stage, at which point the maggot travels away from the food source to a moist spot.
