Along the way, Greg and Patrick also discuss headlamps, airport carousels, prostrate vs. prostate, operatic ambulances, ungulates, how X-mas got its X, Cobra Kai, bromeo, metric time, clang association, paradocies, and William of Orange. 

S3E05: Pop Quiz 3: Ethan's Revenge

Along the way, they also mention: parallelism, Olivia Newton-John, going to the wrong church, laws in Vermont, pick-a-point, nan-aaaah-meters, the whack-a-doodle package of the month, kindergarten math deficiencies, the crossing guard creed, and the rosary landspeed record. 

S3E02: Johnson-Neyman Regions of Significance

In the inaugural episode of Season 3, Patrick and Greg argue (more than usual) about statistical conclusion validity: what it is, what affects it, and how it fits in with other types of validity. Along the way they also mention: FrogFest2021, fostering illusions, coughing up a thorax, entrée vs. entry, 50 hours of community service, 8-hour depositions, statistical herpes, and Cheese Cake Factory menus and calorie counts. Oh, and… the sax is back!

S3E01: Leaping to Statistical Conclusion Validity

In this, the third and final episode of SummerQamp, Greg and Patrick embark on a cross country journey in a VW van in quest of the Summer of Love. Along the way they explore three lines of historical development that ultimately come together to close out the 1960&apos;s: multiple regression, path analysis, and confirmatory factor analysis. They just begin to draw trippy insightful concluding comments but the fuzz show up and break up the party. Harsh. 

A Summer of Love History of Quant, part 3

Nursing their SPF-defying sunburns from SummerQamp 1, Patrick and Greg now find themselves in the woods by a roaring campfire, covered in bug spray. In this second summer installment they transition from previous conversations about the origins of statistics to the incredibly cool and often concurrent history of measurement. Grab a stick, pull up a log, and come roast a marshmallow with us!

A Fireside History of Quant, part 2

After completely blowing an ambitious summer schedule of weekly episodes, Patrick and Greg sit poolside and shoot the breeze about  the fascinating history of quantitative methods. No, for real; it’s actually fascinating. Anyway, they start with some of the old gamblers from the 1600s and work their way through the early decades of the 20th century. This discussion sets the stage nicely for a future summer episode, at least in theory given how long it took to get this one out. HappySummer!

A Poolside History of Quant, part I

S2E33: Truth, Balderdash, and Construct Validity

Greg and Patrick talk about how, although textbooks almost exclusively talk about simple random samples, in practice they almost never actually occur.

Along the way they also discuss killing bugs, Winston Churchill, lies versus omissions, Oprah, signing toast, being conceived in an elevator, strah-TAH, social media polls, the generalizer, the green light button, court-ordered volunteer work, and poopooing. 

S2E32: Lies, Damned Lies, and Random Samples

Patrick and Greg celebrate international haiku day with listener-submitted HaiQs, and somehow tie that to a discussion of team science, all while interviewing intern applicant Ethan McCormick.

Along the way they also discuss honking Diet Coke through your nose, rashes, hostage negotiation, reading at seven months of age, dealer&apos;s choice, Coors Light, Galapagos tortoises, friendly monsters, monkeys at typewriters, umlauts, and shooting stop signs. 

S2E30: ‘Always Center Your Predictors!’ And Other Sh*t My Advisor Says

A podcast dedicated to all things quantitative, ranging from the relevant to the highly irrelevant. Co-hosts Patrick Curran and Greg Hancock talk about serious statistical topics, but without taking themselves too seriously. Think: CarTalk hi-jacked by the two grumpy old guys from the Muppets, grousing about quantitative methods, statistics, and data analysis, all presented to you with the production value of a 6th grade school project. But in a good way.
