George Woodbury (@georgewoodbury) and I have written a Learning Catalytics course to accompany Interactive Statistics 2/e. I started classes this week and immediately started using the program in my flipped class. The level of engagement from my students is enormous and peer-to-peer instruction is taking place. This has increased the level of understanding of my students and created a dynamic Read More …

The General’s Dilemma
Today I am going to do “The General’s Dilemma” activity in my Intro Stats class. I am teaching completely randomized designs, so this is a great opportunity to illustrate the methodology behind this experimental design with this activity. This data will be used to introduce the inferential methods of comparing two independent proportions using randomization methods. Feel free to use Read More …
New York Times Monthly Stats Feature
The American Statistical Association has partnered with the New York Times Learning Network to promote student understanding of graphs. The goal of the feature to help students understand and think critically about graphs. The feature will be called What’s Going on in this Graph? Here is a link to the announcement: https://www.nytimes.com/2017/09/06/learning/announcing-a-new-monthly-feature-whats-going-on-in-this-graph.html The feature will be published starting September 19 and continuing the second Tuesday of Read More …
Quartiles and Boxplots
I just finished teaching Chapter 3 of my text today. To introduce the idea of quartiles and boxplots, I used two data sets. The first is from the PayScale ROI Report. The data set includes annual return on investment, total four year cost, graduation rate, and other variables for all colleges and universities throughout the country. The data is available Read More …
First Week of Classes
Classes have already started here at Joliet Junior College. Last week we had our opening session. The speaker at the session was Valencia Community College’s president, Sandy Shugart. He is a very talented speaker and I took many lessons away from his session. However, there was one point he made that hit me more than any of the others. President Read More …
Introduction to Hypothesis Tests on a Population Proportion
One of the most difficult concepts for students to grasp is that of a P-value. The video below was recorded in my Introductory Statistics class at Joliet Junior College. To introduce my students to P-values, I simulate drawing many (5000) samples from a population built based on the statement in the null hypothesis (this is called the null model). Read More …
Students t Distribution
Do your students understand why we use Student’s t Distribution when performing inference on a mean when the population standard deviation is unknown? I have uploaded a video to YouTube that I recorded in my Intro Stats class. The video uses simulation to motivate Student’s t-distribution.
Co-Requisite Remediation
Here is an interesting study completed within the City University of New York system on co-requisite remediation. They compared three groups using a randomized trial – Elementary Algebra students, Elementary Algebra with Supplemental Instruction, Elementary Statistics with Supplemental Instruction. The 721 participants were randomly assigned to one of those three groups. Guess what? The pass rates for the courses were Read More …
Flipping the Classroom
Have you considered flipping the classroom? The following video illustrates some thoughts.
Learning Catalytics
Below is a video that illustrates how I use Learning Cataltyics in my classroom. Hope you find the program as powerful as I do. Just used it yesterday to review for an upcoming Statistics exam.
