The Correlation Coefficient, usually referred to as ”R” is a way of measuring Linear Relationships. It is calculated using the classpad. The higher it is the ”stronger” a relationship is, if it is negative the relationship correlation is also negative, resulting in the line going in the opposite direction as seen here, however, Correlation ≠ Causation.
Note
if it is a negative relation value is negative
What should be discussed when using
- Form (linear/non-linear)
- Direction (positive/negatve)
- Strength (weak, moderate, strong)
