Comparing Multi-Stage Tests under Different Conditions in Terms of Panel Design, Module Length, Sample Size and Ability Parameter Estimation Methods

Öz

In this research, the performances of multi-stage tests under various simulation conditions have been compared in terms of evaluation criteria, including root mean square error (RMSE), standard error of estimate (SEE), bias, and mean absolute error (MAE). In the test simulation, 81 conditions (3x3x3x3) have been determined, including panel design (1-3, 1-2-3, 1-3-3), module length (6, 12, 18), sample size (300, 1000, 3000), and ability parameter estimation methods (expected a posteriori [EAP], maximum a posteriori [MAP], and maximum likelihood estimation with fences [MLEF]). The research findings indicate that RMSE and MAE values generally produce similar results, and measurement accuracy tends to increase with the lengthening of the module. Additionally, it was observed that RMSE, SEE, and MAE have the highest values in the 1-3 panel design and the lowest values in the 1-3-3 design. Researchers are recommended to conduct their studies using a 1-3-3 panel design, with a minimum module length of 12, and employing the EAP method.

Çok Aşamalı Testlerin Panel Deseni, Modül Uzunluğu, Örneklem Büyüklüğü ve Yetenek Parametresi Kestirim Yöntemleri Açısından Farklı Koşullar Altında Karşılaştırılması

Öz

Bu araştırmada çeşitli simülasyon koşullarında çok aşamalı testlerin performansları, hata kareler ortalamasının karekökü (Root Mean Square Error-RMSE), tahminin standart hatası (Standard Error of Estimate-SEE), yanlılık (BIAS) ve ortalama mutlak hata (Mean Absolute Error-MAE) değerlendirme kriterleri açısından karşılaştırılmıştır. Test simülasyonunda panel deseni (1-3, 1-2-3, 1-3-3), modül uzunluğu (6, 12, 18), örneklem büyüklüğü (300, 1000, 3000), yetenek parametresi kestirim yöntemi (beklenen sonsal dağılım [Expected a Posteriori-EAP], maksimum sonsal dağılım [Maximum a Posteriori-MAP] ve sınırlı en çok olabilirlik kestirimi [Maximum Likelihood Estimation with Fences-MLEF]) olmak üzere 81 koşul (3x3x3x3) belirlenmiştir. Araştırma sonucunda RMSE ile MAE değerlerinin genellikle benzer sonuçlar verdiği ve modül uzunluğu arttıkça ölçme doğruluğunun da arttığı bulunmuştur. Ayrıca RMSE, SEE ve MAE’nin 1-3 panel deseninde en yüksek, 1-3-3 deseninde ise en düşük değerleri aldığı saptanmıştır. Araştırmacılara 1-3-3 panel deseninde, en az 12 modül uzunluğunda ve EAP yöntemi kullanarak çalışma yapmaları önerilmektedir.
