**Fall 2003**

**Computer Problem Set 1**

This assignment asks you to use data from SSAE98 (*Survey
of Student Attitudes and Experiences 1998 *– see the questionnaire from the
Survey and the list of variables handout of September 16, 2003), obtain some statistics from these data and
make comments on the results. When you
have completed 1-6 below, hand in the printout of the SPSS output and the comments. You may wish to copy the SPSS output file to
another program such as Word for Windows, write the comments in that file, and
hand in a paper copy of this.

For each of the following questions, part (a) refers
to what you are to do with SPSS. For
part (b) of each of these questions, write the answers and comments in pen or pencil
on the printout (or in a Word for Windows file).

1. (a)
Obtain frequency distributions for each of the variables COLLEGE, CREDIT, and
PRIORITY by using *Analyze – Descriptive
Statistics – Frequencies*. (b)
In a sentence or two, describe the frequency distribution for each
variable.

2. (a) For each of the first three variables
(free trade, affirmative action, gay couples) in the table at the bottom of the
first page of *Report on the Survey of Student Attitudes and Experiences*,
obtain a frequency distribution and histogram.
(b) Write a note comparing the distributions of these three
variables. Also show how the numbers in
the table in the *Report* were obtained from the SPSS output.

3. (a)
Obtain stem-and-leaf displays for AGE (as dependent variable) by YEAR (factor
list) by using *Analyze – Descriptive
Statistics – Explore* for these
variables. Also, obtain the histograms
of AGE for each YEAR by clicking on *Plots*, then check *Histogram*
and *Continue*, prior to clicking *OK*. (Ignore or delete the boxplot on the output. You could also delete the box giving the
descriptive statistics). (b) Using the
histograms or the stem-and-leaf displays, write a paragraph comparing the
distributions of age by year of program.
Use the stem-and-leaf displays to determine the median and the mode of
age for each of fourth and fifth year students.

4. (a)
For variables V8 and V9, obtain frequency distributions, histograms and
the following statistics: mean, median,
standard deviation, and quartiles. (b)
Calculate the interquartile range.
Using these data, compare the distributions of each of these variables
in words – comment on whether or not responses to the two questions are
consistent with each other.

5. (a)
Obtain all the statistics for the four opinion variables V2, V4, V6, and V7 by
using *Analyze – Descriptive
Statistics – Descriptives*. (b)
Write a short note describing the similarities and differences among the
measures of centrality and dispersion for these four variables.
