Two variables have a positive linear correlation. Does the dependent variable increase or decrease as the independent variable increases? Dependent variable would remain the same Dependent variable increases Cannot determine from information given Dependent variable decreases Two variables have a negative non-linear correlation. Does the dependent variable increase or decrease as the independent variable increases? Dependent variable decreases Dependent variable would remain the same Cannot determine from information given Dependent variable increases Two variables have a negative linear correlation. Does the dependent variable increase or decrease as the independent variable increases? Dependent variable decreases Dependent variable would remain the same Dependent variable increases Cannot determine from information given Two variables have a positive non-linear correlation. Does the dependent variable increase or decrease as the independent variable increases? Dependent variable increases Dependent variable would remain the same Dependent variable decreases Cannot determine from information given A non-linear correlation is when a relationship exists between the independent variable x and the dependent variable y and it is other than linear such as parabolic. 2 What does the variable r2 represent? The population correlation coefficient The critical value for the correlation coefficient The coefficient of determination The sample correlation coefficient What does the variable μ represent? The population mean The sample standard deviation The sample mean
