How can we tell when a frequency distribution is normally distributed.
The frequency distribution below on eye inspection appears to have a normal distribution b'cos :
The frequency starts low and then increase to some maximum then decrease to a low frequency.
Is my observation right?
Thanks

An 'eye inspection' gives you an idea of the sort of distribution you might want to test against.
