* Tests used : WAIS, RAPM, Unknown Mensa Entrance Test, FRT-B.
** Tests used : JCTI, CSE, TLAP-R, JCCES, C-09, C-10.

4. Notes
To sum up, NVRA80 shows high positive correlation with standard supervised IQ tests (r=0.852) and excellent reliability (Cronbach’s alpha=0.903), a fact that makes it a reliable tool for estimating one’s intelligence quotient. Next norm will be generated after a total of 45 submissions.
