Mofule 5 Lesson 5 - Assessing Intelligence Flashcards
Reliability
A measure of whether the results of a test are consistent and repeatable.
Validity
An assessment of whether a test measures what it claims to measure.
Matrix
A rectangular arrangement of numbers or terms having various uses, like transforming coordinates in geometry, solving systems of linear equations in linear algebra, and representing graphs,
Mean
The average of a set of numbers
Median
The middle number in a number series.
Mode
The number that occurs the most in a series of numbers.
Bell Curve
A set of data where the majority of scores are clustered around the mean. Thus, there are fewer scores farther away from the mean.
Standard Deviation
A statistical measure of variance indicating how different a given score is from the mean (average).
Standardized Tests
An exam that is always administered the same way and is scored consistently according to a set of standards.
Stanford-Binet IQ Test
Measures intelligence using fluid reasoning, knowledge, quantitative reasoning, and visual-spatial processing.
Wechsler IQ Test
Measures a person’s ability to adapt.
Mental Age
The intellectual level at which you perform.
Flynn Effect
Over time, the idea of intelligence changes; therefore, the test is recalibrated such that the average score will remain at 100.
What is the Stanford-Binet IQ Test?
Created by a French philosopher Alfred Binet to identify children in French schools that needed assistance with their learning. This test measures…
- Fluid Reasoning
- Knowledge
- Quantitative Reasoning
- Visual-Spatial Processing
- Working Memory
What is the Weschler IQ Test?
Created by Dr. David Wechsler, a clinical psychologist with Bellevue Hospital; in 1939, he created a test to determine a person’s ability to adapt.
How is the Stanford-Binet IQ Test used?
The score is taken from the test and divided by your “mental age” (adults are 20), then multiplied by 100.
How is the Wechsler IQ Test used?
The test for children takes approximately 60-80 minutes to complete. This can be done without any reading, writing, or solving math equations.
The test for adults takes around 90 minutes to complete.
Both tests are verbal and performance-based.
What is the purpose of the Stanford-Binet IQ Test?
It is used to measure your intelligence level. Ex. A high score - 98th percentile - qualifies you for Mensa.
What is the purpose of the Wechsler IQ Test?
A score beyond 130 is considered gifted. Anything below 70 can be determined as a mental functionality.
How do we measure intelligence?
The most common ways are through the Stanford-Binet IQ Test and the Wechsler IQ Test.
How does the Stanford-Binet test report an individual’s intelligence level?
As a quotient (“intelligence quotient”) of their real or estimated mental age divided by their chronological age, then multiplied by 100.
(Mental Age/Chronological Age) x 100
Are Stanford-Binet IQ Tests Linear or Curved?
Modern IQ Tests are not linear, as about 95% of the population scores between 70 and 130 points. A score below 70 typically represents a cognitive deficit while a score above 140 would represent high intelligence. The average score is 100.
What is the Flynn Effect?
Over time, the idea of intelligence has changed so the test is recalibrated to keep the average score at 100. This means that someone who scored 100 in 1980 would score much lower today.

- Needs to be reliable - show the same data
- Needs to be valid - accuracy (cannot be valid if not reliable)
