New to Teaching Intro Stats?
I posted some advice for new statistics instructors, especially those of us in California after AB705. You can Check it out on my Statblog .
2018 StatCrunch Student Contest
On my StatBlog I put together a post about this spring’s StatCrunch contest – check it out here. This is a fun contest for students to use what they are learning in your Intro Stats class and use a set of data to tell a story. There are cash prizes for the top three finishers. Link to the Contest YouTube Conference Announcement Please share with your students. You do not need to be using StatCrunch in your classes – Pearson…
Introducing Hypothesis Testing Through Confidence Intervals
(Sorry for the lack of blogging here … I have two texts in production and it has really slowed me down …) Last week in my Statistics classes we learned to construct confidence intervals for a population proportion and a population mean. On the last day of the week I had students work on a project that contained a mixture of these types of confidence intervals, and then students had to extend their knowledge to use the interval to perform…
One Proportion Tests w/ Binomial P-Values
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…
Flipped Friday – Intro Stats
Last fall I started teaching my intro stats class using the flipped classroom model. I have found many benefits to this approach: My students are more active and engaged in class. I am able to cover much more material than I ever covered before – including simulations, bootstrapping, and non parametric tests. My students level of understanding when it comes to inferential statistics and the “big picture” is higher than ever. I am currently blogging each day, documenting my progress…
Bootstrapping with StatCrunch
The Bootstrap Method The bootstrap method is a very useful tool to have an introductory statistics class. The bootstrap method begins with a sample of size n. Then a large number (I use 10,000 in my classes) of samples of size n are drawn with replacement from that sample. A sample statistic is computed for each sample. A typical use of bootstrapping involves the mean, but this procedure can be applied to the median, quartiles, variance, … Percentiles can be…
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.
Using Facebook Groups In Online Classes
I am teaching an online statistics class this summer, and things are going really well. One reason behind that is the Facebook group page I created for the class. Here are a couple benefits that I have observed. Ability to Contact Students when Course Site is Down Pearson performed some scheduled maintenance on their site during the first weekend of the class. Due to some issues, it took about a day longer than expected. Without the Facebook group, my only…
New Statistics Blog (Fall 2017)
I am starting a new blog to document my day-to-day activities in my introductory statistics classes in Fall 2017, as well as sharing general thoughts on teaching statistics, using Interactive Statistics, incorporating technology, and many other ideas. I will also be sharing classroom materials as I use them. You can check it out here: George Woodbury’s Statistics Blog: https://georgewoodbury.com/statblog/ I have included buttons for following the blog via email or WordPress. George
Case Study of Interactive Statistics in an Online Class
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…
