When the dependent variable is on the y-axis and there is only one independent variable and it is placed on the x-axis, the error term for a given observation is the vertical distance between the observation and the TRUE regression line.
True
False
What is the name for a variable that represents values of only zero and one?
a discrete variable
a time-series variable
a dummy variable
a continuous variable
Homework Answers
1. True
(Error term is the vertical distance between the observation and
the TRUE regression line or the predicted value.)
2. a dummy variable
(A dummy variable takes value only zero and one because it
represents two opposite characteristics.)

The equation of the regression line between two variables x (independent variable) and y (dependent variable) is given by y-hat = -3x + 2; and the correlation coefficient is r = -.95. The possible x-values range from 1 to 10. Which of the following statements are correct? I. The variable y is strongly positive correlated to the variable x. II. The variable y is strongly negative correlated to the variable x. III. If x = 5, one would predict that...

The dependent variable is the position (y-axis) and the independent variable is the time (x-axis). This is the measured position of a rock as it falls from the top of a very high cliff and obeys the equations y = 1/2gt2. Make sure you label the plot properly. Right click on a data point in the graph and add a “Trend line.” Select a polynomial of order 2. This is a parabolic equation and describes an object falling under constant...

11. Multiple regression analysis is used when one independent variable is used to predict values of two or more dependent variables. True or False 13. For a two-tailed null hypothesis, the test statistic Z=1.96. Therefore, the p-value is 0.05. True False

Dummy Variable Regression: Choose any metric variable as the
dependent variable (you can use the same one that you used in Part
A) and choose gender as an independent variable. Also choose one
more metric variable as an additional independent variable. Once
again, however, you must sort through the metric independent
variables until you find one that, along with gender, produces a
significant F-calc. Use alpha = .05 here as well. You
only need to report the model that produced...
