The word correlation is called ‘co,’ meaning together, and ‘relation.’
A correlation is a mutual relationship between one or more things.
Math is often used to discuss the relationship between different data sets.
Correlation in maths
When two or more data sets are linked, they have a high correlation.
Data sets have a positive correlation when they increase together and a negative correlation when one set increases as the other decreases.
Correlation Example
An example of a positive correlation could be that the more hours you exercise, the more calories you burn.
A correlation is if the data sets generally relate to each other, with some exceptions.
Correlation can also be expressed as a value
- 1 is a positive correlation
- 0 refers to no correlation being present
- -1 implies a negative correlation
