OVERVIEW
This worksheet is designed to assess your ability to perform, interpret, report, and graphically present non-
parametric tests using SPSS. Non-parametric tests are used for nominal data and/or when data do not meet the
assumptions required of a parametric test. Knowledge of these tests provide fundamental skills to critically
evaluating and producing research in one’s field.

o Example: SPSS5_JohnDoe_515B01
Scenario 1
In the recent COVID-19 pandemic, a local precinct observed that of the 75 people who voted, 25 identified as
republican, 30 were democrat, and 20 were “other”. Is this similar to pre-pandemic voting based on political
party affiliations? At that same precinct, pre-pandemic voting based on political party affiliation was: 35%
republican, 44% democrats, and 21% “other”. Enter in the 75 data points and expected values into SPSS to
conduct the appropriate statistical test.
1. Name the the variable of interest in the scenario. How many levels does it have, and what are they?
ANSWER
The variable of interest is political party affiliations. It has two levels: pre-pandemic and post-pandemic.
They represent the political party affiliations before and after the pandemic respectively.
2. Calculate the expected frequencies for each of the levels of your variable. Clearly label each group
and show all work involving your calculations.
ANSWER
Frequencies Republican Democrat Other
Observed 25 30 20
Expected 35%*75= 26.25 44%*75=33 21%*75=15.75
