1) Regression:

a) is a statistical technique that is not influenced by outliers.

b) identifies the resistance of a relationship.
c) measures the strength but not the direction of a relationship.

d) can be used for prediction.

2) The best-fitting regression line:

a) has the smallest total standard error.
b) has the smallest slope.
c) has the largest total squared error of prediction.

d) is the line with the smallest (Y – Ŷ)2 value.

If the slope (b) of the regression line equals zero, this indicates:

a) the correlation between the two variables is negative.

b) a perfect relationship between the two variables.

c) a correlation of +1.0.

d) the regression line is horizontal.

The regression line can never be used for prediction. True False The slope is the amount Y changes for every increase in X. True False "When you calculate a regression equation, you want the line with the most error. " True False "Correlation measures the linear relationship between two variables, while a regression analysis precisely defines this line. " True False The predicted value based on a regression equation is a perfect prediction. True False What represents the intercept (the...

Explain why for statistical inference for linear regression and correlation, we perform the inference of the slope of the regression line. Also, why is a null value of 0 considered to be no relationship between the variables? Lastly, how does this relate to 0 being in the confidence interval for the slope of the regression line?

Regression analysis procedures have as their primary purpose the development of an equation that can be used for predicting values on some DV for all members of a population. T F A secondary purpose is to use regression analysis as a means of explaining causal relationships among variables. T F In order to make predictions, three important facts about the regression line must be known. One of them is: The point at which the line crosses the X-axis. T F...

The reason that we obtain the best-fitting line as our regression equation is that we mathematically calculate the line with the smallest amount of total squared error. T F Multiple regression is used to predict the value of a single DV from a weighted, linear combination of IVs. T F The coefficient of determination in multiple regression is the proportion of DV variance that can be explained by at least one IV. T F Multicollinearity is desirable in multiple regression....
