Question

multiple - choice question
what kind of correlation is this?
negative
positive
no correlation

Explanation:

A positive correlation is indicated when the correlation coefficient is positive (here, 0.74). In a scatter - plot (implied by the context of correlation), a positive slope (as would be consistent with a positive correlation coefficient) means that as one variable increases, the other variable also tends to increase. The shared variance (calculated as \(r^{2}=0.74^{2} = 0.5476\approx54.8\%\)) also supports the strength of this relationship, and the nature of the relationship (positive) is determined by the sign of the correlation coefficient.

Answer:

B. Positive
