The research aims to study the psychometric properties of the
standard progressive matrices Test (SPM) to Raven in the Syrian
environment. through using varied methods in studying the Test
validity and reliability, and through the application of the Test on a
sample of first cycle Students in Basic education in Damascus City.
This research aimed to study the psychometric properties of
Standard Progressive Matrices test (Parallel Version), an IQ test
non-verbal measure of intelligence is influenced by culture, this
test was been made in England by John Raven to measure
general intelligence concept Spearman factor, and this is the test
into Englishmen psychologists of the best tools available so far to
measure public factor of intelligence.
This paper is concerned with the calculation of the spectral radius of an
arbitrary real matrix A
If rank A = m = 2 then (١) and (٢) are equalities.
In addition, we provide the numerical radius r(A) of an n×n matrix whose
diagonal entries are complex numbers.
In this paper we consider the properties of linear systems by means of
directed graphs and numerical structures. We also state efficient algorithms
for determining an approximate number of the non-zero terms within
determinants' expressions of the
ir matrices. The stated algorithms make use of
trees representing numerical structures which contains the indices of the nonzero
terms.
This paper yields interesting results used in practical engineering
applications which include linear systems with sparse matrices, for example:
networks, electronic circuits, earth velocities boxes (gearboxes), multi-works
systems ...etc.
