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 mean score is 60 out of 100 and the standard deviation (in other words, the variation in the scores) is 15 marks (see our statistical guides, Measures of Central Tendency and Standard Deviation, for more information about the mean and standard deviation).tandard Normal Distribution and Standard Score (z-score). When a frequency distribution is normally distributed, we can find out the probability of a score occurring by standardising the scores, known as standard scores (or z scores).
