hello #psychology #stats twitter!

a while ago i promised some graphs on why #removing #outliers using a simple cut-off (eg, >2SDs) is a #bad idea

so that I can sleep at night again, here they are

tldr: DON'T (blindly) USE FIXED OUTLIER CUT-OFFS LIKE >2SD. EVER.

for some reason, it's very common in #psychology to remove 'outliers' from data

most common way: exclude data more than two standard deviations from mean

we spend time & money collecting data, then throw 5% away

🤷

I don't know why, or where it's taught, but there it is

It's Good Friday.

As a sacrifice to Science, I'm going to criticise every single paper I've ever written, one tweet at a time.

Stay tuned..!

Paper #1: Holmes & Spence 2004 @xmodal

Criticism: A non-systematic review of selected papers, no assessment of study quality, bias, or effect sizes. The only novel thing in this paper was a long, harsh critique of Iriki et al. (1996)

Paper #2: Skaliora et al. 2004

Criticism: I contributed only one figure (#8) to this paper, but >30 neonatal rats paid the ultimate price for my crappy patch-clamping skills (only 17 cells) as an MSc student. I still feel the guilt.
