AP PSYCHOLOGY

Detailed explanation-1: –0.85 (Option d) is the strongest correlation coefficient which represents the strongest correlation as compared to others.

Detailed explanation-2: -A negative correlation indicates two variables that tend to move in opposite directions. A correlation coefficient of-0.8 or lower indicates a strong negative relationship, while a coefficient of-0.3 or lower indicates a very weak one.

Detailed explanation-3: -A correlation coefficient measures the strength of that relationship. Calculating a Pearson correlation coefficient requires the assumption that the relationship between the two variables is linear. The relationship between two variables is generally considered strong when their r value is larger than 0.7.

Detailed explanation-4: -R2 gives us an indication of how good this fit is. The closer R2 is to 1, the better the equation describes the relationship between the two variables. Earlier I stated that the correlation between these two variables is 0.94, indicating a strong correlation.

Detailed explanation-5: -Correlation coefficients whose magnitude are between 0.9 and 1.0 indicate variables which can be considered very highly correlated. Correlation coefficients whose magnitude are between 0.7 and 0.9 indicate variables which can be considered highly correlated.
