Standardization: In testing, process of evaluating the questions,
establishing the rules for administering a test, and interpreting the scores
Distribution of IQ scores
Isn't as symmetrical as the theoretical normal distribution
More people have scores well below the mean than equally far above it
Mode is higher than the mean
Males shows to be at the extreme top or bottom than females
Females tend to do better in language/memory skills
Males do better in visuospatial rotations
Males focus on one thing at a tie, vs girls who spread their attention more
broadly
Males are more variable
The Flynn Effect
Tendency for performance on IQ test scores to improve from one
generation to the next
Occurs for children who are starting school at age 6
Occurs most strongly on tasks such as the raven's progressive matrices
Occurs least on tests of factual knowledge like material taught in school
Reliability
Repeatability of test scores
Psychologists calculate correlation coefficient
Theoretically range from +1 or 1
In reality, it’s always a zero or positive
Test-retest reliability: correlation on scores of the first test and retest
Validity
Degree to which evidence and theory support the interpretations of test
scores for the intended purposes
How well the test measures what it claims to measure

Document Summary

Standardization: in testing, process of evaluating the questions, establishing the rules for administering a test, and interpreting the scores. Isn"t as symmetrical as the theoretical normal distribution. More people have scores well below the mean than equally far above it. Males shows to be at the extreme top or bottom than females. Females tend to do better in language/memory skills. Males focus on one thing at a tie, vs girls who spread their attention more broadly. Tendency for performance on iq test scores to improve from one generation to the next. Occurs for children who are starting school at age 6. Occurs most strongly on tasks such as the raven"s progressive matrices. Occurs least on tests of factual knowledge like material taught in school. In reality, it"s always a zero or positive. Test-retest reliability: correlation on scores of the first test and retest. Degree to which evidence and theory support the interpretations of test scores for the intended purposes.
