asymptomatic
quality of the normal curve such that the tails never touch
standard score
how many standard deviations a score is from the sample mean
criterion referenced test
where there is a predefined level of performance used to evaluate outcomes
standard error of measurement
quantify how much a test score varies from an individual from time 2 time, from test 2 test
