Correlation is a statistical measure that describes the extent to which two variables change together. It can be positive, negative, or zero.

What is causation?

Back

Causation indicates that one event is the result of the occurrence of another event; it implies a direct cause-and-effect relationship.

A strong positive correlation indicates that as one variable increases, the other variable also increases significantly.

Front

What is a linear model?

Back

A linear model is a mathematical representation of the relationship between two variables, typically expressed in the form of a linear equation.

How do you interpret the slope in a linear equation?

Back

The slope indicates the rate of change of the dependent variable with respect to the independent variable.

What does it mean if two variables have a zero correlation?

Back

A zero correlation means that there is no relationship between the changes in the two variables.
