مقارنة بين طريقتي كيرنل وقوس الدائرة في معادلة درجات اختبار في عينات صغيرة

Abstract EN

The study aimed to compare between Kernel (KE) and Circle-Arc (CA) equating methods in small samples.

To achieve the purpose of the study, two forms of achievement test were constructed, each of them consisted of (25) multiple choice items, each item has four alternatives, using the equivalent groups design to collect data with different samples (15,25,50,100) of female students, selected from the study population which consisted of (741) female students.

The equating accuracy was judged by using the standard error of equating (SEE).

Results showed that (CA) method was more accurate in equating than (KE) method, where the value of (SEE) of (CA) was less than the (KE) method.

Also, Results indicated that values of the (SEE) decrease with the increase of the sample size in both methods.
