Correlation vs. Causation

Front

What is the difference between correlation and causation?

Back

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

Front

Define causation.

Back

Causation is the relationship between cause and effect, where one event (the cause) directly leads to the occurrence of another event (the effect).

Front

What does a correlation coefficient of r = 0.3 indicate?

Back

A correlation coefficient of r = 0.3 indicates a weak positive correlation between the two variables.

Front

Provide an example of causation.

Back

An insect ate poison and it died.

Front

What does a correlation coefficient of r = -0.9 indicate?

Back

A correlation coefficient of r = -0.9 indicates a strong negative correlation between the two variables.

Front

What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables, showing the relationship between them using points on a Cartesian plane.

Front

What does it mean if two variables are positively correlated?

Back

If two variables are positively correlated, as one variable increases, the other variable also tends to increase.

Front

What does it mean if two variables are negatively correlated?

Back

If two variables are negatively correlated, as one variable increases, the other variable tends to decrease.

Front

What is an example of correlation that does not imply causation?

Back

High social media usage and reduced grades may be correlated, but one does not necessarily cause the other.

Front

What is the range of correlation coefficients?

Back

The range of correlation coefficients is from -1 to 1.
