A scaled score of 162 is at the 82nd percentile for all GRE test takers in 2015. Explain what that means
82% of GRE test takers scored 162 or higher
82% of test takers scored below 162
82% of test takers scored above 162
82% of GRE test takers scored 162 or lower
Which is the correct equation for z-score?
z-score = raw score - mean
z-score = mean - raw score / standard deviation
z-score = raw score - mean / standard deviation
z-score = mean / raw score * standard deviation
The mean height for American women is 65 inches (5'5") with a standard deviation of 3.5 inches. Zoe's height 5'1" (61 inches). After computing her z-score (-1.14), we can conclude that
Zoe is 1.14 standard deviations taller than the mean height for women.
Zoe is 1.14 standard deviations shorter than the mean height for women.
Zoe's height is 1.14 standard deviations below the mean height
Zoe's height is 1.14 standard deviations above the mean height
