Explain the difference between a positive correlation

and negative correlation.

Positive correlations: x and y are increasing

Negative correlations: x increase, y decreases

300

There are three main types of correlation:

• _________________________: x & y both increase

• _________________________: x increase, y decreases

• _________________________: there is no relationship between x & y

Positive Correlation

Negative Correlation

No Correlation
