Calculate the expected frequencies for each of the levels of your variable.

Chi-Square SPSS Assignment Instructions

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.

Instructions

Be sure you have reviewed this module’s assigned readings and presentations before completing this assignment. This assignment is worth 50 points. Each question is worth 3 content points except where otherwise indicated (results write-ups are 4 pts each- 45 content points total). Five (5) points are assigned to general formatting. This includes using ensuring the homework is completed and submitted according to the instructions, SPSS output and images are legible and relevant, and that basic college level writing skills (e.g., grammar) are used in the write-ups. Answers should be placed where indicated (e.g., “ANSWER”). Note: all questions must be attempted to be eligible for full credit of “format” points.

· Please note that for all problems in this course, the standard cut-off (alpha) for a test of significance will be .05, and you always report the exact power unless SPSS output states p=.000 (you’d report p<.001). Remember to check your graphs! You often have to ADD the y – axis title.

· Submit the file as a WORD document (.doc or .docx). Make sure the filename of your submission includes your full name, course and section.

· 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

  1. Calculate the expected frequencies for each of the levels of your variable. Clearly label each group and show all work involving your calculations.

ANSWER

  1. Paste all relevant statistical output in the space provided below:

ANSWER

  1. Present the results using APA format. This includes a full write-up to include a complete statistical notation as shown in the weekly presentations. Make sure to describe what the conclusions mean in general terms. Additional examples of APA results sections are also available in the “Helpful Hints” document. (4 pts)
