Z score charts pdf
Z Score Calculation and Z Table Application Example Here is an example of how a z-score applies to a real life situation and how it can be calculated using a z-table. Imagine a group of 200 applicants who took a math test. PSYCHOMETRIC CONVERSION TABLE Standard Score Percentile Rank Scaled Score ETS Score T-Score Z-Score Description 89 23 Low Average 88 21 425 42 -0.75 Low Average 87 19 Low Average 86 18 Low Average 85 16 7 400 40 -1.00 Low Average 84 14 Low Average 83 13 375 38 -1.25 Low Average 82 12 Low Average 81 10 Low Average 80 9 6 367 37 -1.33 Low Average the mean (z-score of 1.645) would be at the 95. th. percentile of a normal (0,1) distribution; 95% of the distribution would be less than this measurement. The following text describes the calculation of z-scores and 'modified z-scores' in the CDC growth charts for BMI values. Similar procedures were used to derive the z-scores and modified The file and corresponding chart names are below: These files contain the z-scores values for the z-scores of –2, -1.5, -1, -0.5, 0, 0.5, 1, 1.5, and 2 by sex (1=male; 2=female) and half month of age. For example, 1.5 months represents 1.25-1.75 months. The only exception is birth, which represents the point at birth.

The area to the RIGHT of a z-score = 1 – the area to the LEFT of the z-score Title Here is a Z Table PDF file that you may need. It’s free for your unlimited use. Example: Actual length 96.1 cm Median 90.4 cm Standard deviation 3.3 Z score = 5.7/3.3 = +1.73 Comparison of growth charts. Percentile graphs have a narrower range, because the 97th centile corresponds approximately to a Z score +2. A Z-score of +3 or -3 is more likely to be definitely abnormal.
