The author of this test and the HRMT that was published previously is Jacek Leluk The author died in 2019. Raw Data 91 people completed the test. 56 people submitted previous PIQ results. The average score was 29.3 SD 4. 7 Regressions RMT vs Average PIQ The following plot is the correlation between HRMT raw score and Average PIQ. Average PIQ was calculated by taking the unweighted average score of all PIQ scores submitted by a testee. The following tests were allowed and utilized in t he calculation: • ANY PROFESSIONAL NON - VERBAL TEST (WAIS, SB, RAIT, Cattell) • Other accepted tests: TRI - 52, Raven’s 2 (Qglobal only), SACFT (ChipDouglas Norm), FRT. The correlation was r = 0. 64 at N = 54 uncorrected. Descriptive Statistics N Minimum Maximum Mean Std.
