A graph entitled ‘Normal distribution (µ = 50, σ = 15)’ consisting of a bell-shaped curve, with a horizontal (x) axis of probability from 0 to 100% and an unlabelled vertical (y) axis. The bell curve indicates a normal distribution with mean of 50 and a standard deviation of 15. As such, it is symmetrical and centred at 50.
