As you can see, performing Bench Dips is very similar to performing regular dips. When you do Bench Dips, grasp the two handles or parallel bars and then place your feet on the support. While keeping your legs straight, raise yourself up until your arms are fully extended, as shown in Figure 8.
All Wechsler Scales, all Woodcock tests, 1 all Kaufman Tests, Most Tests Published by American Guidance Service, Pro-Ed, 2 Riverside, the Psychological Corporation, and Many Others. Z-scores (z), Percentile Ranks (PR), Standard Scores (SS) (Mean = 100, s.d. = 15), Scaled Scores (ss) (Mean = 10, s.d. = 3), and Stanines (9)
The z-score is only defined if one knows the population parameters; if one only has a sample set, then the analogous computation with sample mean and sample standard deviation yields the Student's t-statistic.hus, a positive standard score indicates a datum above the mean, while a negative standard score indicates a datum below the mean.
