Chi-Squared Tests for Two-Way (Contingency) Tables resources
01. Case Study Videos (1)
Case Study Using Chi-squared tests for Contingency Tables
In this case study video, a Chi-Squared test is used to assess whether the type of accomodation university students live in is associated wih their year of study.
The video was scripted by John Marriott (Royal Statistical Society Centre for Statistical Education) and presented by Dr Alun Owen (Loughborough University) and Steve Joiner and Nick Blenkin (both Coventry University).
There are also two accompanying video resources listed with this case study; one which explains the Problem Sovling Approach (PSA) used to handle this type of problem; and another which looks in more detail at how to caclulate expected frequencies when undertaking Chi-Squared tests.

Chi-square test using SPSS, interpretation and significance (assumptions NOT violated)
How to use SPSS to compute a chi-square test for 2-way tables and interpret the output (including coefficient, effect size and corresponding p-value). This resource from the "SPSS Tutorial Series" is contributed to the statstutor Community project by Christine Pereira, Brunel University and reviewed by Cheryl Voake-Jones, University of Bath. It was developed with sigma resource development funding.
03. Teach Yourself Worksheets (4)
Chi-Squared Tests of Association (Worksheet)
This teach yourself worksheet will show you how to perform a Chi-Squared test for association when you have a contingency table formed from two categorical variables. The focus is on hand calculation but also includes some nots on how to do this using SPSS.
Chi-Squared tests of Association Using SPSS (Worksheet)
This yourself worksheet provides an introduction to undertaking chi-sqaured tests of associaton for a two-way contingency table using SPSS. Note that the SPSS data set colours.sav referred to in the worksheet is also available here.
Chi-Squared tests of Association Using SPSS (Worksheet) Data Set colours.sav
This is a zip file containing the SPSS data set called colours.sav for use with Chi-Squared tests of Association Using SPSS (Worksheet). Note: please save this file to your PC before extracting its contents.
Introduction to Hypothesis Testing (Worksheet)
This teach yourself worksheet provides an overview of the framework used in hypothesis (significance) testing.
04. Tests and Quizzes (1)
Business Statistics 5 - Numbas
3 questions. 1. Uses the chi-squared test to see if there is any significant difference in preferences. 2. Find out whether the data presented in this question follows a Poisson distribution. Uses the chi-squared test. 3. The human resources department of a large finance company is attempting to determine if an employee's performance is influenced by their undergraduate degree subject. Personnel ratings are used to judge performance and the task is to use expected frequencies and the chi-squared statistic to test the null hypothesis that there is no association.
