Graph alt text 7

A graph entitled ‘Standard normal distribution’ consisting of a bell-shaped curve, with a horizontal (x) axis of values from -3 to +3 and an unlabelled vertical (y) axis. The solid line bell curve indicates a normal distribution with mean of 0 and standard deviation of 1. As such, it is symmetrical and centred at 0, dropping smoothly to almost zero at -3 and +3.
