Practice Using Z Scores What information is provided by the sign (+/-) of a z-score? What information is provided by the value of the z-score? o e.g. z = -2.5; z=+1.4 A distribution has a standard deviation of sigma = 6. Describe the location of each of the following z-scores in terms of relative position to the mean. For example, z = +1.00 is a location that is 6 points above the mean. o z = +2.0 o z = +.50 o z = -2.0 o z = -.50 For a population of scores with mu = 50 and sigma = 8 o Find the z-score for each of the following X values. X = 54 X = 62 X = 52 X = 42 X = 48 X = 34 For the same population find the x score that corresponds to each of the following z scores: o Z = 1.0 o Z = .75 o Z = -1.50 o Z = -.25 o Z = 1.5

Find the z-score corresponding to a score of X = 60 for each of the following distributions: o Mean = 50 and s = 10 o Mean = 50 and s =20 o Mean = 50 and s = 5 o Mean = 50 and s = 2
What is the z-score that o separates the 10 % of scores from the bottom 90%?
