Distribution Curves
Variables such as height, weight, shoe size, exam results, and IQ scores – all tend to show normal distribution when plotted on graphs.
In Psychology, this information can help researchers make assumptions about the way in which populations are distributed.

The mean, median and/or mode all are shown in the centre at the highest peak. 3 characteristics of normal distributions

Can you apply these 3 characteristics to a graph AND then say what this says about the population / sample?
