Practice: Measuring Dependent Variables: Types and Scales of Measurement

This is a brief in-class practice activity (created by Raechel Soicher) to help students review different types of measurement for dependent variables as well as identify scales of measurement. Raechel recommends teaching about the different ways to measure a dependent variable before giving students the opportunity to review using this brief worksheet. She provides definitions …

Practice: Having Fun with Operational Definitions

One of the challenges instructors face when discussing conceptual and operational definitions of variables is helping students to understand that the operational definition of a variable involves measuring the variable in a concrete, quantitative manner. The practice activity asks students to identify the relevant variables of interest and then suggest ways that these variables can …

Practice: Calculating the Pearson r Correlation (Video Games and GPA)

Instructors should assign this problem (about how many hours per week they played video games and their GPA) to students as in-class practice or homework after students have learned how to calculate a Pearson r correlation and test for significance.

The activity leads students through determining the type of statistical analysis to use, the hypotheses, calculating the t-ratio and effect …

Practice: Calculating the t-test for Paired-Samples/Dependent Means (Drugs and Learning)

Instructors should assign this problem (about drugs and learning) to students as in-class practice or homework after students have learned how to calculate a t-test for dependent means and test for significance. The activity leads students through determining the type of statistical analysis to use, the hypotheses, calculating the t-ratio and effect size (if appropriate), …

Lecture Slides: Measuring Dependent Variables

This  lecture introduces students to several different ways of measuring   behavior as the dependent variable.  Several types of behavioral measures are shown, including: behavioral trace, behavioral observation, and behavioral choice. The goal of this lecture is to get students to see other types of measuring DVs, aside from self-report. This starts with a quick overview …

Lecture Slides: Manipulating Independent Variables

This  lecture introduces students to several different ways of manipulating independent variables. Some techniques covered include: mock Facebook profiles, priming, having participants count money, and viewing cute pictures. The goal of this lecture is to get students to see a variety of ways that researchers can manipulate IVs. Each example provides the citation for the …

Assignment: Creating a Conference Poster on Sex Differences (SPSS)

In this assignment (created by Dr. Kimberly A. Barchard and Dr. Leiszle Lapping-Carr), students conduct a literature review, analyze data using an independent samples t-test and a confidence interval, create a grouped frequency distribution and a histogram, write a research report, and create a PowerPoint poster. A detailed grading rubric is included. This assignment was …

Example Syllabus – Statistics with Lab

A sample syllabus for an introductory statistics course. Though this course has a lab, that content could also go into the lecture portion of the course, or incorporated as something students do outside of class as group projects. The syllabus also describes a statistical presentation assignment, as well as a Statistics Portfolio where students curate …
