Canadian IQ on WAIS IV

#1
The Canadian IQ calculated from the standardization of the WAIS IV


Abstract
The Canadian standardization sample of the WAIS IV obtained a Full Scale IQ 104.5 in relation to 100 for the American standardization sample, giving Canada a British (Greenwich) IQ of 102.5.

Key Words: WAIS IV, Full Scale IQ, Canada, Intelligence.

This is pretty much in line with PISA Creative Problem Solving, whose score converts into a Greenwich IQ for Canada of 101.4, the highest among Western countries, only topped by northwestern Italy's IQ at 102.5 and by East Asian countries (https://docs.google.com/spreadsheets/d/1...sp=sharing).
Actually you may want to cite that PISA CPS score in this paper. This is what future studies should do, start using PISA CPS for what it is, probably even better than Raven's at assessing fluid intelligence (and certainly more representative). After you do that, I'll approve.

Do you have the IQ scores by gender group ? Is it possible to publish these numbers ? Also, if you have the correlations, standard deviations and means for each of the WAIS-IV subtests, that will be pretty good for people who want to use MGCFA on that data.

I don't have it by gender group but i do have it for other subtests and can include that.

Can you upload the dataset?

The paper type should be "Short communication".

Quibble: "The result confirms the four previous studies showing that the Canadian IQ is approximately the same as the British": In national IQ research, especially with regard to European diaspora countries, a difference of 2.5 IQ points is fairly significant, so this sentence should be amended to read "...slightly higher...". Other than that quibble, this paper is good and should be accepted.

I think it's better than nothing to report those numbers. Still, without group membership, I can't use MGCFA because the technique needs means, SD and correlation for every groups (i.e., men and females) so you must have 2 matrices.

(to be clear, MGCFA works with covariance, not correlation, but you can transform correlation into covariance and inversely if you have the SD; most packages (LISREL, R, AMOS/SPSS) do this transformation)

I agree with Philbrick, especially in light of the PISA CPS results, the Canadian IQ does seem to be slightly higher than the European IQ. I wonder if this is due to the ethnic composition, there seem to be a lot of Asians (not specified whether it's East or West Asians though), so this can partly explain the slight advantage compared to the US (with lots of Blacks) or Europe (with lots of north Africans). It would be also good if you could add a sentence or two to the discussion section, discussing about why the Canadian IQ is a bit higher (possibly due to racial composition). Here is what I found on Wikipedia for Canada:
76.7% European
14.2% Asian
4.3% Aboriginal
2.9% Black
1.2% Latin American
0.5% Multiracial
0.3% Other

Are there results broken down by race?

I guess "Asians" may refer to Amerindian natives.

I was thinking the same myself and this would be congruous with IQ predicting immigration: i.e. Canadians are the descendants cleverer British people. But, on the other hand, when you match the Canadian sample with a US one of the same race/class/ etc then the Canadian Greenwich IQ is reduced to 100.13, as indicated in the paper. Surely, this is not significant.

No, they're not. But, as we said in the paper, when the match the US sample and the Canadian sample on race then the difference almost disappears and you get a Greenwich IQ of 100.13. So this would imply the reason is Asians. I will add this into the paper.

I can include all the raw scores etc that have been requested.
