Back

A negative relationship indicates that as one variable increases, the other variable decreases.

Front

What is a correlation coefficient?

Back

A correlation coefficient is a numerical measure that describes the strength and direction of a relationship between two variables.

Front

What does a correlation coefficient of +1 indicate?

Back

A correlation coefficient of +1 indicates a perfect positive correlation between two variables.

Front

What does a correlation coefficient of -1 indicate?

Back

A correlation coefficient of -1 indicates a perfect negative correlation between two variables.

Front

What does a correlation coefficient of 0 indicate?

Back

A correlation coefficient of 0 indicates no correlation between the two variables.

Front

What is the difference between correlation and causation?

Back

Correlation indicates a relationship between two variables, while causation indicates that one variable directly affects the other.

Front

How can you identify a strong positive relationship in a scatter plot?

Back

A strong positive relationship is identified by points that closely follow a straight line that slopes upwards.

Front

How can you identify a weak negative relationship in a scatter plot?

Back

A weak negative relationship is identified by points that are scattered but generally trend downwards.
