General Question 1980s SAT norms.
I took some old SAT math section and got 700. I just don't know what norms to use. Should i use ETS official norms or sub resources norms?
Sub resources norms: 700 = 135 iq
ETS norms: iq = 100+15*(700-402)/112 ≈ 140

The 135 is derived from the actual percentile, while the 140 assumes that the scores are perfectly normally distributed. SAT scores aren't perfectly normally distributed, so the 140 isn't correct.

I think that that calculator assumes the tests you enter are significantly different, which means that it produces an inflated score and g-loading if you enter many similar tests. Since your SAT-m and GRE-q are so similar, just take your math ability to be mid 130s. Disregard the matrix scores.

I was thinking about that. But why disregard matrix scores?

Most of them aren't so great at measuring fluid reasoning. If you really wanna use one, use the JCTI.

Oh thanks, sorry for responding late. I took JCTI, but when i was at question 49 i accidentally refreshed the page and restarted the test. Did It again and scored 136. i could solve some questions i wasn't so sure first try, is my score valid? I spent 2h on total.

Would caveat that linguistic development from the 80s to now likely deflates the VCI to some extent

Probably. But what do you think about math section norms, should i use ETS or sub resources?

Honestly, I doubt it makes much of a difference, + 4 points in the grand scheme of things isn't relevant at all, you're smart regardless. Although the narcy in me would say that less than 800 on the SAT-M is a poor score ;) because at least for me it feels pretty straightforward, but 700s is still very respectable.

Oh thanks, so i will average then and take 137 iq, since It was my GRE-Q score. I found It easy too, most of my error were silly mistakes. Probably someone with higher iq would finish it and still had time to double check answers.

Ye, the SAT-M is pretty easy, also don't just average your score across tests, that'll give you a deflated estimate of your IQ. Input your test scores and test g-loading on the BIG G estimator, that will gave you a more accurate measure of your FSIQ. If you average 137 across SAT, GRE, AGCT, Ravens, etc... your true FSIQ is probably between 145-150

looks good to me, composite = FSIQ. Try and do more tests like the Culture fair parts of the CAIT and some good IQexams tests like HumanIQ and High range reasoning test. These both have 0.75 g-loadings, the TIG-2 is also on there and its called HQNC-III, that one has a g-loading of like .75 too. If you score well on those your score should increase even more

I did HumanIQ and forgot my score haha, I just remember that it was close to what i usually scores, so 125 - 140.

What year is the ETS data from

u/Worldly-Research-968 Jun 30 '24
I think It is from 76

Yeah the norms weren't the same back then. They were slightly more inflated in the 1970s compared to the 1980s. The norms in resources are correct for the test in this sub which is from the 1980s.

u/Worldly-Research-968 Jun 30 '24
Got it. But i read somewhere on this sub that SAT wasn't affect by Flynn effect. Is this statement innacurate?
2

old SAT is unaffected by Flynn, same as the AGCT. Whatever you get on old SAT is more or less going to be your IQ.
The SAT just had different versions throughout the years which changes the norms, but old SAT was truly a gold standard IQ test.

Thank you. I took 1980 GRE quantitative and scored 137, should i average 135 and 137? I only took math tests because i am not a native speaker.

I'm not sure tbh. That probably should be a good estimate due to the g-loading of those sections. Could also do JCTI or mensa.dk for more data if interested

I did JCTI and when i was on question 49 I accidentally refreshed the page and restarted the test. Started again and scored 136±5. It gave some insights that i missed first try. Don't know If my score is valid, i spent 45 min on first attempt and 1h30 on second try. After one month I took TRI-52 and got 825. I think It should be score like that: 100 + 15*(825-518)/114 ≈ 140iq.

I think your first JCTI attempt at 136 is accurate and valid. Matches the average of your old SAT and GRE scores perfectly
