A relationship between two variables: positive when they tend to increase together, and negative when one tends to decrease as the other increases.

An association between two variables: positive when they tend to increase together, and negative when one tends to decrease as the other increases.

On a scatter graph, examine whether two variables tend to increase together, move in opposite directions or show no clear relationship. This is correlation. A relationship between two variables does not, by itself, prove that one causes the other.

An association between two variables: positive if they tend to increase together, negative if one tends to decrease as the other increases.

A relationship between two variables in which their values tend to change together.

An association between two variables; this does not by itself show that one causes the other.

A relationship between two variables: positive when they tend to increase together, negative when one tends to decrease as the other increases.

A relationship between two variables: positive correlation means they tend to increase together; negative correlation means one tends to decrease as the other increases.

An association between two variables. Positive correlation means they tend to increase together; negative correlation means one tends to decrease as the other increases.

Do not claim that correlation proves causation, or remove an inconvenient result without justification.

Describe what the graph shows before suggesting an explanation. Correlation alone does not prove cause and effect.

Distinguish a general trend from an anomaly, and do not assume that correlation proves causation.
