Using New Interpretation Charts
All of the possible scores that fall into the range of data provided in Appendix A have been analyzed and plotted, using the “Standard Scale” (Mean and S.D.). The scores are presented in the form of a color-coded bar graph. The bar graph represents a normal distribution or bell curve, but the actual curve is not shown. The colors indicate the gradations of performance based on the “Verbal Scale.” Note: This is illustrated in Figure 1 on page 33.
To utilize the new interpretation charts, identify the appropriate chart for the occupational area that best describes the subject. Refer to the proper bar graph for data regarding each test battery. Locate the subject’s raw score or the average of 3 trials. Evaluate the score using the verbal scale, the standard scale, or both. Look at the top of the bar graph for the verbal score. The sections are color coded for convenience. The subject’s raw score can also be used to determine how many S.D. above or below the Mean the sore falls. Read the S.D. from the outside inward. Notice the arrows in the example chart (Figure 1) on the page 33.
