What is intelligence factor analysis?
intelligence theories In human intelligence: Psychometric theories. …these performance differences, Spearman devised factor analysis, a statistical technique that examines patterns of individual differences in test scores. He concluded that just two kinds of factors underlie all individual differences in test scores.
Who is known as father of factor analysis?
L.L. Thurstone, considered the father of factor analysis, uses 60 terms across 1300 subjects to arrive at five broad factors.

What is Charles Spearman theory?
Spearman concluded that there is a single g-factor which represents an individual’s general intelligence across multiple abilities, and that a second factor, s, refers to an individual’s specific ability in one particular area (Spearman, as cited in Thomson, 1947).
What is G in IQ?
The g factor (also known as general intelligence, general mental ability or general intelligence factor) is a construct developed in psychometric investigations of cognitive abilities and human intelligence. The g factor targets a particular measure of general intelligence.
What are the two main forms of factor analysis?
There are two types of factor analyses, exploratory and confirmatory. Exploratory factor analysis (EFA) is method to explore the underlying structure of a set of observed variables, and is a crucial step in the scale development process.
What are factor scores?
Factor scores are composite variables which provide information about an individual’s placement on the factor(s). Once a researcher has used EFA and has identified the number of factors or components underlying a data set, he/she may wish to use the information about the factors in subsequent analyses (Gorsuch, 1983).
How did Spearman measure general intelligence?
Terms in this set (15) How did Spearman measure general intelligence (g)? He inferred g from tests of various abilities, such as vocabulary, memory, and reasoning. Who proposed the existence of fluid and crystallized intelligences?
What are the 10 multiple intelligences?
1 Linguistic Intelligence (“word smart”)
Is IQ and g factor the same?
The terms IQ, general intelligence, general cognitive ability, general mental ability, and simply intelligence are often used interchangeably to refer to this common core shared by cognitive tests. The g factor targets a particular measure of general intelligence.
Why is the general intelligence factor important to factor analysis?
Introduced at the turn of the century by British psychologist Charles Spearman, factor analysis determines the minimum number of underlying dimensions necessary to explain a pattern of correlations among measurements. A general factor suffusing all tests is not, as is sometimes argued, a necessary outcome of factor analysis.
What was Raymond Cattell’s theory of two factor intelligence?
Raymond Cattell expanded on Spearman’s idea of a two-factor theory of intelligence after performing his own tests and factor analysis. He used a multi-factor theory to explain intelligence. Cattell’s theory addressed alternative factors in intellectual development, including motivation and psychology.
Which is the best description of factor analysis?
What is factor analysis ! Factor analysis is a theory driven statistical data reduction technique used to explain covariance among observed random variables in terms of fewer unobserved random variables named factors 4
What is the purpose of factor analysis in GIS?
The statistical extraction of gis performed by a technique called factor analysis. Introduced at the turn of the century by British psychologist Charles Spearman, factor analysis determines the minimum number of underlying dimensions necessary to explain a pattern of correlations among measurements.
