A) Grouped scores
B) Independent scores
3. Statistical Properties & Correlations with other tests
Calculated mean on reported scores on standard supervised tests is 141.1 sd15 (N=28). Mean raw score of this sample on ISRC2018 is 19.071.
|Parameter||Value||Test||Score Pairs (n)||r|
* Tests used : WAIS, RAPM, IBF-S, OLSAT, CFIT20R, CCFIT, FRT, Unknown Mensa Entrance Test.
** Tests used : JCTI, CSE, TLAP-R, JCCES, C-09, C-10, Encephalist, NVCPE-R, C-12, EPC-L.
To sum up, SEE30 shows very high positive correlation with standard supervised IQ tests (r=0.802 – It has to be noted at this pointed that scores “greater than”, like >135 that are given in FRT-A case are used when computing validity. Not including those ones could lead to a much higher r.) and excellent reliability (Cronbach’s alpha=0.898), a fact that makes it a reliable tool for estimating one’s intelligence quotient. It’s also quite clear, yet still preliminary as an observation, that there is a stronger correlation with spatial tests, something that was, more or less, expected. Next and final norm will be generated at a total of 120 submissions, although no significant changes are to be expected.
