Thread: MBE percentile and grading for raw score or scaled score + essay grading for AZ

  1.   MBE percentile and grading for raw score or scaled score + essay grading for AZ #1
    Does anyone have a MBE percentile chart for both the raw score or the scaled score? I read that a letter from AZ gave a range of the AZ takers 94 - 185. The reported AZ average was 145.2. I know that the July MBE typically is 143 average. If someone can provide a formula or a chart, it will be very highly appreciated. Also, does anyone know how the "essay scaling" process works for AZ

    a good tool

    Salmon Chase, author of the blog "Sometimes you eat the bar" introduced this tool: http://bayes.bgsu.edu/nsf_web/jscrip...ormal_icdf.htm

    and calculated the percentile (for raw score I believe)

    * 141 = 95th percentile
    * 140 = 94th percentile
    * 131 = 86th percentile
    * 130 = 85th percentile
    * 129 = 84th percentile
    * 108 = 47th percentile
