WARNING
First,
warm thanks to Greg A. Grove,
Ph.D.who has drawn up the norms of the Beta version of the 916
Thanks
too to the following persons for their remarks and suggestions
Obviously,
thanks too to all the test takers
Greg
made the calculus on the raw (expected answers) and on the relative (non expected
but pertinent answers) scores. I intended to post norms for relative score
only, but it appears that norms based on raw score are more accurate and
significative with regard to the IQ of the test takers and the consistence of
the items, which is excellent; the instability of some items has been corrected
by some precisions in the Warning of the 916 test; except few items, it appears
that the entire test is highly satured in g factor.
Nevertheless,
actual norming remains an approximation, even if a good one!
The
following data have to be made relative but they give a good idea of the
difficulty of the test
despite
of his apparent simplicity.
My
apologize for my approximate English
Two boards:
-the first one with RAW (my answers) and RELATIVE (non expected but pertinent
answers) SCORES and IQ of the most part of the test takers in Deviation 16.
-the second
board with the Number of test takers who have solved an item with the expected answer and the Number of
test takers who have solved an item with non expected but pertinent answer and
the total in the last colon.

Before I
post the test, the following items had been submitted to more than 2000 persons
(my students; average IQ around 100)
C7 has been solved by about 20 persons only
C8 has been solved by about 200 persons
C11 has been solved by about 20 persons only
C13 has been solved by 2 persons only
C14 has been solved by 1 persons only
C15 has been solved by 1 persons only (his
apparent instability in the 916 will easily corrected by adding one number)
The
consistence of the items is excellent despite of the instability of some of
them; but except A7 and C4 which are bad items as it appears in board 2, the
light instability of the others has been corrected by precisions in the Warning
of the 916.

1) To norm the test I removed all the test
results that didn't have IQ
scores
provided, plus persons 3 and 9 because of extreme scores.
2) This resulted in a norming population of 16.
N = 16

Here is how
various High IQ clubs did on the test:
916 mean IQ

Mysterium
mean IQ = 140.3
916 mean IQ

Mensa mean

Cerebrals
mean IQ = 144.8
916 mean IQ
= 152.0
Glia mean IQ
= 153.3
Overall
means:
N = 13
916 mean IQ
= 142.5
HIQ clubs
mean IQ = 143.2
The
correlation between the 916 and 13 members
of the
above High IQ clubs = r .982
The
internal consistency of the items in the 916 exam is r = .986

My work
with the two scoring systems, the raw scores (based on your answers)
and the
pertinent scores (based on nearly correct or different but
plausible?),
showed the raw scores to be the better of the two. There is
approximately
a 3 point difference between the raw average and the pertinent
average. A few individuals made tremendous gain
toward healthier scores on
the
pertinent, but when correlated with IQs, the difference between the raw
vs. IQ and
pertinent vs. IQ was .50 vs. .54. Not
significant.
The raw
scores correlate .98 with Mensa IQ scores.
That is remarkable!

Use Raw
Scores for this set of data. I took the
four groups (Mysterium,
Mensa,
Cerebrals, and Glia) and used them only to generate the following.
The results
are impressive and may well be the most accurate when providing
insight
into the high IQ society's performance on the 916. From prior
studies
with the High IQ membership, the average IQ is 139, as testified as
well by Dr.
Ron Hoeflin's Mega norms and average.
