SPSS Project #1
The goal of this assignment is to obtain summary statistics for several variables of the
GSS 2002 data set. This is an important part of most statistical studies. In your report,
clearly label all tables and graphs, and when appropriate, give the units of measure.
For each of the following variables, submit a written summary. The summary should
include a frequency distribution and a graph (such as a bar chart or pie chart for
categorical variables or histogram for numerical variables). Discuss whether the
distribution is heterogeneous or homogeneous. Include the measures of central tendency
that are applicable to each variable.
Variable “tvhour” (in GSS 2002 - part a)
Variable “rcregion” (in GSS 2002 – part a)
Variable “happy” (in GSS 2002 – part b)
Your report should be in article form and should look professional. In particular, it should
be typed in Microsoft Word and your tables and graphs should be integrated with your
text. For clarity, you may want to include an introduction and a conclusion. Make sure to
explain your answers thoroughly. Your grade will be based both on mathematical content
and presentation.
For extra credit, investigate the question whether men are generally happier than
women, according to our GSS 2002 (part b) survey.
Tips for a good Report
Describe the overall question(s) you are investigating.
Describe your data. Is it a random sample? Where did the data come from? Is it
“reputable”? What is the sample size N?
Give an overview of the variables you are investigating. Use proper terminology
to describe them (nominal, ordinal, numeric) but make it clear in “plain English”
what your variables measure.
Describe the distribution of variables – homogeneous or heterogeneous? Use
charts and/or tables as appropriate. Point out anything special about a distribution,
if applicable.
Use at least one chart and one table, but don’t use too many charts or tables
Mention the number of missing cases and whether it is “good” or “bad” for your
analysis
Give each table and chart a descriptive name, explaining what the table/chart
represents. If necessary, explain clearly what you did to obtain the table (e.g. split
data according to sex into two groups, male and female).
Explain the main features of any table and chart in words.
Your report should have an introduction, a main section, and a conclusion if
necessary.
