Correlation describes the connection between two sets of data.
We have seen that as the temperature increases then the number of ice-creams sold also increases. If plotted, the results will approximate a straight line having a positive gradient. We therefore say that there is a ‘Positive Correlation‘.
Sometimes two variables are unconnected such as the ‘Height of a Pupil’ v’s ‘Month Born’. If plotted there would be ‘No Correlation‘.
The strength of the correlation can also be described as ‘weak‘, ‘moderate‘ or ‘strong‘ depending on the scatter graph cluster.
