As a member of the Interactive Metronome Scientific Advisory Board I am often asked to review published research studies that have investigated the IM method.

The citation and abstract for the article are reproduced below.

In a prior post I provided access to a special IAP AP101 Report on the standard error of measurement (SEM).  Over at IQ’s Corner sister blog ( ICDP ) a follow-up IAP 101 Brief was published entitled “How likely is each score in an IQ SEM confidence band likely to represent the person’s true IQ?”  Click here to view this report that provides a nifty little SEM probability cheat-sheet.
