Answer #1

We know that the correlation coefficient between two variables depends on their data sets, but does not depends on the dependent variable or independent variable

so,we can say that correlation coefficient r is independent from variable type

Slope is defined as the change in y or dependent variable per unit change in the independent variable

so, it does matter for the slope that which variable is independent and which is dependent variable

therefore, we can write

It DOES NOT matter which is the explanatory/independent variable and which is the response/dependent variable for correlation coefficient r, but it DOES matter for slope

Of the two variables, HighJump and LongJump ,which do you think should be the explanatory variable and which should be the response variable? Or, does the choice not matter, as neither is “prior” to the other?

A regression between foot length (response variable in cm) and height (explanatory variable in inches) for 31 students resulted in the following regression equation: y = 22 + 0.18 x. One student in the sample was 73 inches tall with a foot length of 29 cm. What is the predicted foot length for this student?

For the purposes of testing for a correlation, does it matter which variable is labeled X and which is labeled Y? A. No it does not matter; the estimate of a correlation (and correlation test) is symmetric. B. Yes, it does matter; the strength of the correlation (and the result of the correlation test) will depend on which you variable you pick as the explanatory variable.

Regression ____ (b values) indicate how much influence each independent variable has on the dependent variable. Regression analysis serves two main purposes: to define the relationship between variables and to ____ values of the dependent variable using what we know about the existing correlation between the variables. The coefficient of multiple determination, R^2, is interpreted as the percentage of ____ in the dependent variable that is explained by the independent variable.
