Correlation vs. Causation

Front

What is correlation?

Back

Correlation is a statistical measure that describes the extent to which two variables change together. A positive correlation means that as one variable increases, the other also increases, while a negative correlation means that as one variable increases, the other decreases.

What is causation?

Back

Causation indicates that one event is the result of the occurrence of another event. In other words, causation implies a cause-and-effect relationship between two variables.

What does a correlation coefficient of 0 indicate?

Back

A correlation coefficient of 0 indicates no correlation between the two variables, meaning changes in one variable do not predict changes in the other.

What does a correlation coefficient of 1 indicate?

Back

A correlation coefficient of 1 indicates a perfect positive correlation, meaning that as one variable increases, the other variable also increases in a perfectly linear manner.

What does a correlation coefficient of 0.19 suggest about the relationship between two variables?

Back

A correlation coefficient of 0.19 suggests a very weak positive correlation, indicating that there is little to no relationship between the two variables.

What does a correlation coefficient of 0.92 indicate about studying and grades?

Back

A correlation coefficient of 0.92 indicates a strong positive correlation, suggesting that as the number of hours studied increases, grades tend to increase as well.

What is the difference between correlation and causation?

Back

Correlation does not imply causation. Just because two variables are correlated does not mean that one causes the other. Other factors may influence the relationship.

Front

What is a scatterplot?

Back

A scatterplot is a graphical representation of two variables, where each point represents an observation. It helps visualize the relationship between the variables.
