Flashcards in Modules 32-33 Deck (17)
Started modern intelligence testing by developing questions that would predict children's future progress in the Parish school system.
IQ = mental age/chronological age • 100
Are intended to protect your ability to learn a new skill and future performance.
Are intended to reflect what you have already learned.
Standardizing a test involves administering the test to a representative sample to a future test takers in order to establish a basis of meaningful comparison.
Standardized tests establish a normal distribution of scores on the test and population, a bell shaped pattern called the normal curve.
In the past 60 years intelligence scores of Studley risen by an average of 27 points, a phenomenon known as the Flynn effect.
When I test you will consistent results. To establish reliability researchers must establish different procedures, such as split half reliability, reliability using different tests, and test-retest reliability.
Split half reliability
Dividing the test into two equal halves and assessing how consistent the scores are.
Reliability using different tests
Using different forms of the test to measure consistency between them.
Test retest reliability
Using the same test on two occasions to measure consistency.
Refers to what the test is supposed to measure or predict. Content validity or predictive validity.
Refers to the extent a test measures a particular behavior or treat. For example of course final.
Refers to the function of the test and predicting a particular behavior or treat. Predictive power of aptitude scores weekends as children grow older.
People that have an IQ of below 70, and are required constant supervision a few decades ago but with support a family environment in special-education cannot care for themselves.
Studies of twins, family members, and adopted children together support the idea that there is a significant genetic contribution to intelligence.
