What does a correlation coefficient of 0.19 indicate?

Back

A correlation coefficient of 0.19 indicates that there is no significant correlation between the two variables being analyzed.

Front

What does a correlation coefficient of 0.92 indicate?

Back

A correlation coefficient of 0.92 indicates a strong positive correlation between the two variables, meaning that as one variable increases, the other variable also tends to increase.

What does an r-value of -0.89 indicate?

Back

Front

What is a strong positive correlation?

Back

A strong positive correlation occurs when two variables move in the same direction, and the correlation coefficient is close to +1.

Front

What is a strong negative correlation?

Back

A strong negative correlation occurs when two variables move in opposite directions, and the correlation coefficient is close to -1.
