I love the idea that these blobs are dull enough to be entertained by flipping coins, but clever enough to cheat at it.

[LegoEngineer]

Imagine being the 3% of cheaters that had a weighted coin and still got only tails

[subtlewhatssubtle]

I shared this with several of my former professors and they loved it.

By far the one who had the funniest reaction was my sociology professor, who said "ensure the false positive rate is less than 0.1%." I asked him why, at which point he smiled this giddy evil smile and said "Then have the cheaters get labeled as mangoes."

[bensaunders]

I leverage significance testing pretty heavily in my day-to-day job, and really loved the way you broke it down here! Particularly appreciate framing statistical power (true positive rate) on the same level as significance (false negative rate), when in most cases the conversation/focus really only extends to significance/p-vals. Going to spend a few minutes scrolling through to purge some of these spambots clogging up the comments, then on to the next vid :)

the blobs have really evolved - from effectively wild creatures to gambling addicts

[cardoso]

Am I dreaming? A new Primer video? Can’t be.

[hotscottrulz]

I love this blob society. They only have one cop, and that cop’s only job is to find people who cheat at coin-flipping.

Middle school me wishes there was a youtube channel or a teacher that made math as entertaining or as understandable as Primer does

[jasonwallace]

Love this video. I teach a graduate-level class on experimental design, but many of the students have forgotten a lot of the basic statistics by the time they take it. I'm bookmarking this as a potential reminder/class aid. Thanks!

[matheusborges]

I love how you take (sometimes boring) statistics concepts and explain them in a way that makes it simple and enjoyable for non-maths guys.
Good job, my dude.

[ThePeacockHeir]

I dont even watch these to learn a subject better, i just watch and listen to this for fun! Its actually pretty entertaining!

[stathelp]

I'm in love with idea how you approach the concept of frequentist hypothesis testing, which confuses so many. (from a statistics teacher). I will definitely recommend your video whenever we come to this part of the curriculum.

[thought-provoker]

Let's say: if a cheater feels that someone is onto them, they will secretly switch to a fair coin.
Then, we're suddenly very deep in the domain of games theory.
A simple crossover that shows how quickly mathematical models become complex.

[arislanbekkosnazarov]

My heart aches for those wrongly accused blobs

[KittyGamingtheBestYoutuber]

I thought I was gonna watch blobs with infidelity.

[mertturk]

Your out-of-the-box thinking and unique perspective turned an otherwise mediocre presentation into a fantastic one *johnson spy* . You did a good job of catching the mistakes and keeping us from wasting time and by taking the wrong path. Your attention to detail really sets you apart from the crowd. Great work! Jack, Your great work has resulted in tangible, beneficial results to me. You’re a force to be reckoned

[RedLuigi]

Given that the parameters are the game are: "The blob who flips heads feels happy, " it might be possible that there are actually secret (deviant) tail-lovers amongst the blobs, who routinely cheat to "lose" more than expected.

I love how your the only YouTuber that makes the zoom to fit look good! Thank you for making my day!

[Leo_Dragontamer]

I first watched this video before taking a stats class. I now watch it halfway through a stats class and understand it so much more.(first learning about power this week!)
