Standardization

Reliability
a numerical index of the degree of relationship between two variables.
A correlation coefficient
refers to the ability of a test to measure what it was designed to measure.
Validity
refers to the degree to which the content of a test is representative of the domain it’s supposed to cover.
Content validity
is estimated by correlating participants’ scores on a test with their scores on an independent criterion (another measure) of the trait assessed by the test.
Criterion-related validity
the extent to which there is evidence that a test measures a particular hypothetical construct.
construct validity
A child’s _______ indicated that they displayed the mental ability typical of a child of that chronological (actual) age.

Emotional intelligence
correlations among many variables are analyzed to identify closely related clusters of variables.
Factor analysis
a symmetric, bell-shaped curve that represents the pattern in which many characteristics are dispersed in the population.
Normal distribution
scores that locate participants precisely within the normal distribution, using the standard deviation as the unit of measurement.
Deviation IQ
indicates the percentage of people who score at or below the score one has obtained.
