Question

a set of data is shown to have a correlation coefficient of 0.15. what does this signify about the relationship between the data?
a there is a strong positive linear correlation between the x values and y values.
b there is a weak positive linear correlation between the x values and y values.
c there is a strong negative linear correlation between the x values and y values.
d there is a weak negative linear correlation between the x values and y values.

Explanation:

Correlation coefficients range from -1 to 1. A positive value means a positive linear relationship, and values close to 0 indicate a weak correlation. Since 0.15 is positive and near 0, it represents a weak positive linear correlation.

Answer:

B. There is a weak positive linear correlation between the x values and y values.
