One Proportion Tests w/ Binomial P-Values

One Proportion Tests w/ Binomial P-Values

Comments 0 Comment

Last fall I began using an approach to incorporate inferential techniques into my Intro Stats course much earlier than I used to. (Hat tip to Matt Davis from Chabot College in CA for the inspiration to do this.) I began using simulations, randomization, and bootstrapping to start exploring statistical inference. I introduced my students to the concept of confidence intervals and evaluating claims about population parameters based on sample evidence. I first formalize the hypothesis testing language and procedure with…

Statistics Blog – Week 1

Statistics Blog – Week 1

My first week of day-by-day blogging is complete. If you’d like to see where I go in week 2, including an introduction to inferential statistics through simulation and randomization, check out the blog here: https://georgewoodbury.com/statblog/. I created the blog to discuss the power of Interactive Statistics, Interactive Reading Assignments (read a little, watch a little, do a little), Learning Catalytics, StatCrunch, and the Flipped Classroom. I promise you will find tips and tools that will increase student learning.

I’m really proud of this latest study involving our Interactive Statistics (I am a co-author with Michael Sullivan) by Sam Bazzi at Henry Ford College. I saw Sam present his results at ICTCM and was really impressed. I encourage you to check out his case study. Read the Study Here This reinforces the fact that there is not a better product to use in an online statistics course: students persisted at higher rates and their test scores improved as the…

I have had a few questions about how I am managing to work all of these early inferential projects into my Intro Stats course. 1) Switching from Chapter Exams to a Midterm and a Final In the first 7 chapters of our textbook I used to give 4 exams. That means that I would use 4 days for exams and approximately 6 days for review. I have 4 days built into my calendar for review (2 days) and the midterm…

This semester I have incorporated a three-pronged strategy in my intro statistics classes: Flip the classroom – having students learn material at home Make the classroom more engaging – using more group activities and Learning Catalytics sessions Focus on early inferential statistics early and often This week began with students learning about the 5-number summary and how to create a boxplot. On Monday we did an activity where students compared two samples of quantitative data in an effort to determine…

As part of my effort to bring inferential statistics to the beginning of the semester I had students work through their first inferential project. This occurred on the sixth day of instruction. Simulation for a Population Proportion On the previous day we were going over different ways to display qualitative data (frequency tables, pie charts, bar charts). We created a pie chart for a sample of 60 students and it showed that two-thirds of those students were female. I asked…

My 3 R’s and Mindset

My 3 R’s and Mindset

I took last semester off (bank leave), so Monday will be the first day teaching students in about eight months. What did I do during that time? I worked on the three R’s: resting, reading, and redesigning my classes. Resting I have taught a full load of classes every semester (and nearly every summer) since I started at College of Sequoias back in 1994. I did not think I needed a break because I did not feel the burnout that…
