5) What does Percentile 18 – P18 mean?
{ 1111122222333334445
18 have scored fewer than 5 6) Please refer to the norm provided below and interpret the scores – 10, 20 and 24
9 10 11 12 13 14 15 16 20 21 22 23 24
30% 32% 33% 38% 40% 44% 48% 50% 64% 68% 70% 85% 90%
7) Indicate the drawbacks of the Percentile in the figure given below:
8) Standard Score is a linear transformation derived by using the formula: (Raw score – Mean score (of a standard sample)) z= (Standard Deviation (of a standard sample)) If Mean score is 14 and Standard Deviation is 4, find a z score for raw scores of 15, 8, 14 & 20 and plot it on the graph given below:
9) T Score is obtained by using T = 50 + 10*z with 50 as Mean and 10 as Standard Deviation Plot T scores for z = 0, 1, -1, -3
10) The range of the z score is –3 to +3 and so the range for T score is 20 to 80, this is obtained by T = 50 + 10 * (-3) = 20 and T = 50 + 10 * (3) = 60 (50 being Mean and 10 as Standard Deviation). For Dr. Natarajan’s T modified score, we use 16 as Standard Deviation, what would be the range of score for this derived scores? 11) List out a few challenges while building norms.
