Practical Statistics: Significance Testing of Nominal Data
Are you looking for a way to evaluate whether something has changed significantly or not? This session will focus on testing whether the count of something is significantly different than expected. In-class examples will use actual data to compare the number of students answering assessment questions correctly in SP-12 to previous years. The session is intended to be non-technical, and will present a "cookbook" method for comparison using Microsoft Excel . A working knowledge of Excel is required.
Outcomes:
Participants will be able to-
• Understand the use of the Chi-Square test and what it measures
• Learn in which situations to use the Chi-Square test
• Discuss examples drawn from assessment data where the test of significance was applied
• Use Excel to perform the Chi-Square test with assessment data
• Correctly interpret data and draw conclusions from this test of significance
