What does relationships between variables mean?
A correlation is the measurement of the relationship between two variables. These variables already occur in the group or population and are not controlled by the experimenter. A correlation simply indicates that there is a relationship between the two variables.
How do you classify variables?
Classifying variables can be somewhat contentious. Standard statistical textbooks will state that variables can be broadly classified as categorical or continuous. Categorical variables can be further categorised into nominal (e.g. ethnic group), ordinal (e.g. tumour staging) and dichotomous (e.g. sex).
