David is doing research

• Culture is cool
• Reading (theory-driven, top-down knowledge building), and doing interviews with international teaching assistants (evidence-driven, bottom up knowledge building)
• Example: American classrooms use discussion and interruption, and it’s not considered rude. (We “know” things by explaining them.) Asian classrooms don’t rely on discussion nearly as much, and teacher’s can fail to recognize reticence to contribute as a cultural proscription rather than an intellectual fault. (“Knowing” is implicit.)

 

Adam is busy at school; needs some denial

 

Hyperupic

• It translates pictures into sound
• Adam says it’s not available for download, but I don’t know… Try googling it. It looks like you can get it if you email the creator.
• Or try a newer alternative:
  • SonicPhoto (PC only)
  • PhotoSounder (PC/Mac)
  • MetaSynth (Mac and I think PC)
  • And if you click nothing else, check out this link: itismorefuntocompute
  • Seriously, look at that link.

 

• Other interesting computer music stuff
  • Game of Thrones Theme done analog:
  • South Park Game of Thrones theme
    • Yeah. I'm not linking to this.

 

Points of Clairy

1. False positives
• David said that false positives come from noise in the data. I suppose that’s possible, but I misspoke. Generally speaking, noise in the data is going to obscure your ability to detect a signal. The reason why you might get a false positive is more likely to be due to sampling error.

Stopping rules

You keep testing, and looking at your results, until you get what you want. Bad scientist. And a little bit of truth inflation added in for good measure.

 

Regression to the mean

Or aggression to the mean?

 

As always, our major source of inspiration on this topic: Statistics Done Wrong by Alex Reinhart

 

Conjunction fallacy

The Linda Problem
Heuristic: We answer with a plausible solution, not a probable one.

 

Sound Science

Computer program allows the blind to see with sound

Seriously cool
And here's the video.

Not to mention eye music !

TED Push

Oops. We went too long. Next week!

 

Next time!

1. Validity and reliability
2. Summarize the stats? Soon!
