Correlation
A mathematical technique in which a researcher investigates an association between two variables, called co-variables
1 of 5
Co-variables
The variables investigated within a correlation, e.g. height and weight. They are not referred to as the IV's and DV's because a correlation investigates the association between the variables, rather than trying to show a cause & effect relationship
2 of 5
Positive correlation
As one co-variable increases so does the other. E.g. the number of people in a room an noise are positively correlated
3 of 5
Negative correlation
As one co-variable increases the other decreases. E.g. the following two co-variables: number of people in a room and amount of personal space are negatively correlated
4 of 5
Zero correlation
When there is no relationship between the co-variables. E.g. the association between the number of people in a room in Manchester and the total daily rainfall in Peru
