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)
A z score always reflects the number of standard deviations above or below the mean a particular score is. For instance, if a person scored a 70 on a test with a mean of 50 and a standard deviation of 10, then they scored 2 standard deviations above the mean. Converting the test scores to z scores, an X of 70 would be: So, a z score of 2 means the original score was 2 standard deviations above the mean. Note that the z distribution will only be a normal distribution if the original distribution (X) is normal.
