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)
Divide by the number of scores (minus one if it is a sample, not a population): The mean of this value is given by 1464/5 = 292.8. The number in between the brackets is the variance of the data. Ï = â[292.8] Square root the total: To calculate standard deviation, we take the square root â(292.8) = 17.11. Ï = 17.11.
