Mofule 5 Lesson 5 - Assessing Intelligence

Question 1

Reliability

Answer 1

A measure of whether the results of a test are consistent and repeatable.

Question 2

Validity

Answer 2

An assessment of whether a test measures what it claims to measure.

Question 3

Matrix

Answer 3

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,

Question 4

Mean

Answer 4

The average of a set of numbers

Question 5

Median

Answer 5

The middle number in a number series.

Question 6

Mode

Answer 6

The number that occurs the most in a series of numbers.

Question 7

Bell Curve

Answer 7

A set of data where the majority of scores are clustered around the mean. Thus, there are fewer scores farther away from the mean.

Question 8

Standard Deviation

Answer 8

A statistical measure of variance indicating how different a given score is from the mean (average).

Question 9

Standardized Tests

Answer 9

An exam that is always administered the same way and is scored consistently according to a set of standards.

Question 10

Stanford-Binet IQ Test

Answer 10

Measures intelligence using fluid reasoning, knowledge, quantitative reasoning, and visual-spatial processing.

Question 11

Wechsler IQ Test

Answer 11

Measures a person’s ability to adapt.

Question 12

Mental Age

Answer 12

The intellectual level at which you perform.

Question 13

Flynn Effect

Answer 13

Over time, the idea of intelligence changes; therefore, the test is recalibrated such that the average score will remain at 100.

Question 14

What is the Stanford-Binet IQ Test?

Answer 14

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

Question 15

What is the Weschler IQ Test?

Answer 15

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.

Question 16

How is the Stanford-Binet IQ Test used?

Answer 16

The score is taken from the test and divided by your “mental age” (adults are 20), then multiplied by 100.

Question 17

How is the Wechsler IQ Test used?

Answer 17

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.

Question 18

What is the purpose of the Stanford-Binet IQ Test?

Answer 18

It is used to measure your intelligence level. Ex. A high score - 98th percentile - qualifies you for Mensa.

Question 19

What is the purpose of the Wechsler IQ Test?

Answer 19

A score beyond 130 is considered gifted. Anything below 70 can be determined as a mental functionality.

Question 20

How do we measure intelligence?

Answer 20

The most common ways are through the Stanford-Binet IQ Test and the Wechsler IQ Test.

Question 21

How does the Stanford-Binet test report an individual’s intelligence level?

Answer 21

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

Question 22

Are Stanford-Binet IQ Tests Linear or Curved?

Answer 22

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.

Question 23

What is the Flynn Effect?

Answer 23

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.

Question 24

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.

Answer 24

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