Talk:2755: Effect Size

Wasn't something like this actually done?

Robert Sapolsky mentions an obscure paper that actually did something like this. They did a meta-analysis of the average reported error throughout various disciplines in order of the physical size of the objects being studied (e.g., from cells to organs to etc.), and found no correlation between them. The conclusion was that this was evidence that philosophical reductionism was flawed. Fephisto (talk) 22:45, 27 March 2023 (UTC)

Did you manage to find it? 172.70.57.203 08:49, 28 March 2023 (UTC)

But does the meta-analysis include itself? Technically, it too is part of Science... Artinum 172.70.91.151 13:06, 28 March 2023 (UTC)

scroll box location is ~25.5% down track: scroll box is 10px high, scrollbar is 290px high, 54px above box, 226px below = center of scrollbox is 59/231 = 25.541..% = ~209,815 pages of total studies. Adjusted to 210,000 to account for rounding errors. (Plus the scroll box might not even move a pixel for a number of pages).162.158.146.41

Did anyone notice the asterisk next to one of the graph elements? There's got to be a lot of those... Not all scientific studies (I would say very few) can be boiled down to a single numerical output.162.158.146.41

Unless I misunderstand this, there's also an aspect of this that's due to sign - because some studies of some outcomes expect negative results, and some expect positive, mixing even results that are overall statistically significant may cause the effects to cancel out.
