Abstract:
The purpose of this research was to study the characteristics and construct
norm of intelligence by the Colored Progressive Matrices (CPM) and the Advanced
Progressive Matrices (APM) in Thai students aged 6-18 years in the eastern region.
Chanthaburi is representative province. The samples were 1,682 students (CPM 612,
APM 1070). Statistical analysis used was reliability (KR-20), item analysis, construct
validity by factor analysis, descriptive statistics, t-test and F-test for comparing means
of difference variables, and construct of a normative scores table of intelligence.
Results revealed that the quality of CPM had high reliability (.92), the range of
item discrimination from .24 to .68, mean of discrimination (.52) differentiate between
high group and low group, the range of item difficulty from .33-.97, mean of difficulty (.74)
being rather easy. The statistics showed standard error of measurement (SEM) 2.03, mean 27,
median29, mode34, standard deviation 7.17, maximum 36, minimum 3 and skewed -.895 and
the mean scores of CPM in sex group were not significantly different but the mean
scores of CPM in each age group and educational level were significantly different at
.05. The quality of APM has high reliability (.87), the range of an item discriminates
from .08 to .62, mean of discrimination (.43) differentiate between high group and low
group, the range of an items difficulty from .07-.87, mean of difficulty (.51) being
moderate. The base of statistic results showed standard error of measurement (SEM) 2.38,
mean 18.71, median19, mode19, standard deviation 6.61, maximum 35, minimum 1 and
skewed -.357 and the mean scores of APM in each sex group, age group and
educational level were significantly different at .05.
The results led to construct a specific normative scores table of intelligence by
CPM in Thai students eastern region age 6-11 years old divided by age, educational
level and construct a specific normative scores table of intelligence by APM in Thai
students eastern region age 12-18 years old classified by sex, age, and educational
level. Both of the normative scores tables have been transformed to percentile and IQ
score. This study suggests that IQ score should use the norm table follow the nature of
subject which are age norm or level of education norm
