This 50 question fill-in worksheet is related to a unit or lesson on Chi Square Test Procedures. The worksheet is a good 'startup' activity to introduce and/or supplement an existing discussion on three chi square test of hypothesis procedures for goodness of fit, independence, and homogeneity of proportions. You may use the activity as independent learning or allow students to table share as a quick collaborative startup activity for a unit on chi square test procedures for categorical and frequency count data. Alternatively, the document can be used as a formative assessment midway through a module or unit on chi square test procedures. Or, you may simply distribute the answer key to students as a preview or summary of key concepts about chi square test of hypothesis procedures. This document can be used by one teacher at one school. If you would like to share it with a friend, please direct them to our store or purchase an additional license.
