Second Research Project

The goal of this project is to conduct univariate and bivariate analysis on a set of
variables of your choosing. The project requires you to know (a) what statistics to calculate for
variables measured at different levels, (b) how to calculate these statistics using the SPSS
the statistical software package, and (c) how to interpret the results of descriptive and inferential
statistics.
The first step in the project is becoming familiar with how to access and perform
statistical calculations in SPSS. In our session today, we have introduced the basics of using
SPSS. In addition, there are screenshots and video tutorials attached located in the folder for
today’s session. Note that SPSS is available in computer labs throughout campus. You can click
on this link (http://acadtech.gwu.edu/locations) to identify specific locations where SPSS can be
accessed (under “Search by Software”).
The second step is choosing variables that you will use for your statistical analyses. In
class today, we introduced the States data set. This is the data set you will be using for your
project. You will select one variable from the data set to serve as the dependent variable in your
calculations. You will also select three variables from the data set that will serve as independent
variables in your calculations. You will select your dependent variable and independent
variables from the 153 variables contained in the States data set. The codebook for the States
data set, which attached to the module for today’s session, provides basic information about
these 153 variables.
The third step is to calculate univariate statistics for your dependent variable and
independent variables. If the variable is measured at the ratio level (as most variables are in the
States data set), then you will calculate the median and mean as your measures of central
tendency, and the range, interquartile range, and standard deviation as your measures of
dispersion. If the variable is measured at the ordinal or nominal level, then consult with me to
determine which univariate statistics you should calculate.
The fourth step is to conduct bivariate analyses of the associations between your
dependent variable and each of the independent variables. Since you have three independent
variables, you will calculate bivariate statistics for three different pairs of variables (i.e.,
dependent variable paired with the first independent variable, dependent variable paired with the second
independent variable, dependent variable paired with third independent variable). If both
variables in a pair are measured at the ratio level, then calculate the correlation coefficient as
your measure of association (i.e., as your measure for gauging the direction, strength, and
statistical significance of the association). If one or both of the variables in the pair is measured
at the ordinal or nominal level, then consult with me to determine which bivariate statistics you
should calculate.

The fifth step is to save the output of your univariate and bivariate analyses. Our class
session today, as well as the screens shots on the module for today’s session, provide information
about the steps to follow to save the output of analyses conducted in SPSS.
The sixth step is to produce a write-up where you report on the results of your univariate
and bivariate analyses. In this report, you should introduce which variables you have selected
for analysis. In addition, you should discuss why you have selected these variables and what
hypotheses you have regarding the associations between your dependent variable and each of
your three independent variables. You should then interpret each of the univariate statistics that
you have calculated. What information do these statistics, both individually and collectively,
convey about the central tendencies and dispersions of each of your variables? Next, interpret
each of the bivariate statistics that you have calculated. What information do these statistics
convey about the direction, strength, and statistical significance of the associations between your
dependent variable and each of your independent variables? Finally, present a brief summary
statement of what lessons, in an overall sense, the statistical analyses have provided about the
variables that you have studied. What kinds of questions for further analysis have been raised by
your univariate and bivariate analyses?
The project is due at the beginning of class on November 25. The write-up and SPSS
output must be submitted at that time in hard copy form. The write-up (excluding the SPSS
output) should be no longer than 5 double-spaced pages, using a 12-point font and 1-inch
margins. Any project not handed in this manner and by that time will be subject to the late
penalty stated on the syllabus.
