Brittany Haynes Kin 3502 Section 5 I.D. 99 KIN 3502: Tests and Measurement in Kinesiology Stats Lab 2: Percentile, Standardized Scores 1. Calculate the percentile rank for your individual scores for both the BMI and the 1 Rep Max. PR= cum% above X + (% for X/2) BMI PR 18 = 2.8 + (15.9/2) = 10.8% 1 Rep Max PR 65 = 28.6+ (2.9/2) = 30.1% 2. Calculate the z- and T scores for a BMI score of 24. (Formulas, text, page 43). Z= (X-Mean)/ S = (24-23.2)/ 3.3 =0.24 T=10Z + 50 = 10(.24) + 50 = 52 3. Calculate the z- and T scores for a 1 Rep Max of 95 pounds. Z= (95-125.5)/83.1 =-0.37 T= 10(-.37) + 50 = 46.3 4. Calculate standard scores (the z-score and the T score) for your scores on both the 1 Rep Max and BMI (formulas are on page 43 of your text). BMI Z= (19-23.21)/ 3.3 = -1.3 T= 10(-1.3) + 50 =37 1 Rep Max Z= (65-125.5)/ 83.1 = -0.73 T= 10(-.73) + 50 = 42.7 5. Calculate the z- score and the T score for your 1 Rep Max score using the class mean from another year, which is given below. Compare your standard score in the current data set to the standard score for the other year. What conclusions can you draw by comparing those two scores?
