A Better, Stronger, Statistics Tool
Intellectus Statistics™ (IS) offers an easy to use resource to integrate IS into an introductory statistics or quantitative methods course. Here’s a 5-Step idea to create a stats assignment. This resource presents a template to create unique assignments using the raw output, interpreted output materials, and the data sets for significant results.
To integrate Intellectus Statistics™ into coursework, use the following 5-steps to create an assignment. Choose from among 24 statistical tests, use the practice dataset or use your own data. Below is an example of how one could teach a chi-square test of independence statistic.
1. Provide the Intellectus Statistics™ chi-square table and raw output.
2. (a) Have students write-up the null and alternative hypothesis.
(b) Provide the students with the interpreted narrative (below) to fill-in blanks (Note: instructor can choose what information to delete).
(c) Have student summarize the result of the study in 1 sentence.
Chi-Square Test of Independence Example
A Chi-Square Test of Independence was conducted to examine whether DxPre and DxPost were independent. There were 2 levels in DxPre: ______ and ______. There were 2 levels in DxPost: ______ and ______. Prior to conducting the analysis, the assumption of adequate cell size was assessed, which requires all cells to have expected values greater than ______ and ______ % of cells to have expected values of at least ______. All cells had expected values greater than zero, indicating the first condition was met. A total of ______ of the cells had expected frequencies of at least five, indicating the second condition was met.
The results of the Chi-square test were not significant, χ2(__) = ____, p = ____, suggesting that DxPre and DxPost [are/are not] independent of each other. This implies that the observed frequencies were [significantly/not significantly] different than the expected frequencies.
3. Let students validate their interpretation by providing Intellectus Statistics™ auto-generated write-up.
4. (a) Using new data, provide only the Intellectus Statistics chi-square table and raw output. Have student write-up the entire findings narrative. (b) Have student summarize the result of the study in 1 sentence.
5. Provide students Intellectus Statistics™ auto-generated write-up to validate their work.
