Writing Assignment
Two

Please
answer the following question in 6-8 pages of double spaced normal font with
one inch margins. Assignment is due in class on October 23, 2012.

Question 1

Now
that we understand bivariate regression it is time to expand our knowledge
base. I would like you to apply the skills you displayed in the previous
assignment in a multiple regression format. To demonstrate our multiple
regression mastery locate some data with three interval level variables (note:
you can use the practice data sets in STATA). Run a regression with two or more
independent variables. Write up the results of your analysis.

In this write up you need to basically do
everything that you did previously but with a few additions. First brie y describe
the variables used and what they are measuring. Include a small table that
presents the mean, maximum, minimum and standard deviation values for all of
your variables. Describe the relationship you would expect to nd, i.e. your
research and null hypothesis. Be sure to state these hypotheses in the
appropriate format, i.e. null b=0. You need to do this for each independent
variable. Second, describe your results including writing out the estimated
equation for the line. Be sure to discuss the following issues; statistical
signi cance of parameters and overall model. You should also calculate an
F-test and include a discussion of the results (don’t just report the F-test
provided in STATA), relationship between independent and dependent variables,
and the amount of variance that is explained. Third, you need to include a
table of the results. This should consist of a table you created with the
appropriate statistics included from the STATA analysis. DO NOT just print out
the STATA analysis and attach it to the paper. Do not include the con dence
intervals and speci c levels of con dence that STATA gives you. You should look
at this when digesting your analysis but it is generally redundant information.
Simply designate signi cance at the 95% level of con dence with an asterisk.
Fourth, include a scatter plot of the bivariate relationship between each
independent variable and the dependent variable. Fifth, use your equation to
make some substantive predications about the relationship you found. At this
point do not worry about examining the regression assumptions, we will delve
into that in the next assignment.

Lastly, lets try to nd
some politically relevant data so that we are actually applying our regression
skills to what we study.
