		.87
		-.92
		.55
		-.76

Answer 1

## For which of the following Pearson's r values is the proportion of shared variance between variables the largest?

Answer :  

the proportion of shared variance between variables the largest = r square value

here for r = 0.87 then r square value = 0.87² = 0.7569 that is in percentage equal to 75.69 %

here for r = - 0.92 then r square value = - 0.92² = 0.8464 that is in percentage equal to 84.64 %

here for r = 0.55 then r square value = 0.55² = 0.3025 that is in percentage equal to 30.25 %

here for r = - 0.76 then r square value = -0.76² = 0.5776 that is in percentage equal to 57.76 %

## the proportion of shared variance between variables the largest for r = -0.92 ie r square = 84.64 %
