Question

1. If the value of r is -0.83 for a dataset comparing two variables, what does that tell us?We can say that the correlation is (positive or negative) and (strong or moderate or weak or negligible).

Answer 1

• Negative

,

• Strong

Step-by-step explanation:

Correlation coefficients are indicators of the strength of the linear relationship between two different variables, x, and y.

The value of r usually ranges from -1 to 1. If the correlation coefficient is less than zero, it is a negative relationship.

• Thus, for a dataset with r=-0.83, we can say that ,the correlation is negative.

Next, values between -1.0 to -0.70 suggests a strong negative correlation, since -0.83 is between -1.0 to -0.70, therefore, it is a strong negative correlation.

Therefore, we can say that the correlation is negative and strong.
