I.I. QUALITY MATRIX (from August 2012)

   I realized an importance of item quality and so all my future tests will be carefully prepared through IVIQ competitions.

   NEW:
   Correlations with Logima Strictica 36 by Robert Lato can be found HERE.

   After 20, 40, 80 and 120 testees, together with new norm reports, I'll publish detailed statistical information about quality of each test.
   First of all, I give some notes and explain my procedure.

   S=number of points achieved by all testees on a particular item
   R=number of points achieved by the best S testees

   For each solved item I'll calculate the ratio R/S.
   This ratio would ideally be equal to 1, and otherwise less than 1.

   If this ratio will be 0.7 or above, an item will be qualified as good, and that item can measure approximate intelligence quotient (AIQ).
   If this ratio will be lower than 0.7, an item will be qualified as average, and that item can measure only specific intelligence quotient (SIQ).
   If this ratio will be lower than 0.5, an item will be qualified as suspicious, and that item can measure only knowledge-dependent intelligence quotient (DIQ).
   If this ratio will be lower than 0.3, an item will be qualified as bad, and that item can measure only mystical intelligence quotient (MIQ).

   An overall quality of each test will be calculated as average ratio of all solved items. Quality in the certain range (130-150, 140-160 or 150-170) will be calculated too.
   Top three tests in each range are highlighted. Read more...

* Hard items are easily qualified as bad on a low sample of testees. Accurate estimates are expected for final norm reports.

Second attempt average improvement: 7% (based on more than 200 submissions)
