4/8/24 New

The final presentations and videos for Test 2 are now posted.

In ANOVA you will find the following notes and videos (all denoted with New):

• Regression and ANOVA Equivalence
• Two-way ANOVA
• ANCOVA

In summary, Test 2 will cover presentations on

• statistical control and adjustment
• standardized regression coefficients
• regression with both quantitative and categorical variables
• One-way ANOVA
• Two-way ANOVA
• ANCOVA

3/30/24

Part of the material for Test 2 is posted now, and the remaining will be posted soon.

In regression find the following notes and videos

• Statistical control and adjustment
• Standardized regression coefficients
• Regression with both quantitative and categorical variables

For the new material, see item 6 Regression with both Quantitative and Qualitative Preditors below.

Test 2 will cover material from the above presentations, plus a few ANOVA presentations (one already posted, two or three more to follow) 

Course Index (e.g., tests, activities, reading and other material to review for each class session)

1. Syllabus
2. Course Calendar - see below.
3. Readings, presentations, and videos are found linked in the Course Calendar.
4. All submitted material must be the PDF form. You can often save word processing documents as a PDF using "File-> Save as" but if this option does not work for you, see this page for other options: Creating PDF Files
5. Below are MS Word documents with developed tables and sample written results in APA style. Use of these documents allows one to copy and paste developed tables without having to recreate those tables.

1. Regression

• Regression: One Qualitative Predictor with Two Categories 
• One Qualitative Predictor with Three or more Categories 
• Multiple Qualitative Predictors 
• Multiple Quantitative Predictors 
• Both Qualitative and Quantitative Predictors 

2. ANOVA

• One-way ANOVA
• Two-way ANOVA without Interaction
• Two-way ANOVA with Interaction
• One-way ANCOVA
• Two-way ANCOVA
• One-way ANCOVA with Covariate by Factor Interaction

3. Structural Equation Modeling (to be added)

6. Test 1: Covers introductory material and regression models. Test 1 due tbd  
7. Test 2: Covers ANOVA/ANCOVA models and equivalent regression models. Test 2 due tbd
8. Test 3: Covers SEM models. Test 3 due 4/29
