Ronald Hoeflin reports:

As of July 1, 1996, 33 people have attempted the Ultra Test. Their scores, on a scale of 0 to 72 (with verbal problems counting one point and nonverbal problems counting two points, with half a point for slightly incorrect verbal answers), were as follows:

9 | 34 | 51 |

14 | 36 | 52 |

16 | 36 | 59 |

17 | 37.5 | 62 |

27 | 38 | 62.5 |

28 | 41 | 64.5 |

30 | 43.5 | 65 |

30 | 45 | 67 |

30 | 47.5 | 68 |

30.5 | 49.5 | 68 |

34 | 50 | 68 |

The median score (50th percentile) was 41 and the mean score was 42.74, or rounded off 43. There were 79 usable scores from previous tests reported, yielding 79 pairs of scores, the other half of each pair being the score achieved above on the Ultra Test. I arranged each group of 79 scores in numerical order from lowest to highest, smoothed the rough edges a bit, and arrived at the following norms for the Ultra Test. IQ's are based on a normal distribution curve and 16 IQ points per standard deviation. Some extrapolation and interpolation was required, of course, to arrive at these results.

Regarding the last five problems in the Ultra Test, the spatial sequences, the performance of the 33 participants, when they are divided into the top eleven scorers, the middle eleven scorers, and the bottom eleven scorers on the test as a whole, looked like this:

The top eleven scorers had a 64 percent success rate (i.e., they solved a total of 35 right out of 55
attempted problems)^{1}, the middle eleven scorers had a 25 percent success rate (i.e., they solved a
total of 14 problems out of 55), and the bottom third had a success rate of 16 percent (i.e., they were
successful a total of 9 times out of 55 attempted problems).

For problem 50, the top eleven all successfully solved the problem; the middle eleven were successful 7 times out of 11; and the bottom eleven were successful 5 times out of 11.

For problem 51, the top eleven were right 4 times out of 11; the middle third were successful 2 times out of 11; and the bottom third were successful 1 time out of 11.

For problem 52, the top third were successful 9 times out of 11; the middle third were successful 5 times out of 11; and the bottom third were successful 2 times out of 11.

For problem 53, the top third were successful 4 times out of 11; the middle third were successful 0 times out of 11; and the bottom third were successful 0 times out of 11.

And for problem 54, the top third were successful 7 times out of 11; the middle third were successful 0 times out of 11; and the bottom third were successful 1 time out of 11.

^{1} That is, the top 11 in overall score averaged 3.2 correct on the last five problems. -- DTM
