Pelaksanaan Analisis Data Menggunakan Model Pengukuran Rasch bagi Menentukan Wajaran Item (Implementation of Data Analysis Using Rasch Measurement Model for Determining the Weights of Items)

Abstract

Acquisition of adequate and meaningful research data, as well as the appropriate analysis is important in ensuring the strategic direction and objectives of the study are well achieved. Data analysis is an important element in any study. Good data analysis is obtained from the study that is carefully planned based on an appropriate design, as well as the approach that is used in the process of analysing the data. The objective of the study to be conducted is to determine the weight of criteria for sustainable construction. Therefore, the right selection of data analysis is very important to ensure that the objectives are successfully achieved. This manuscript writing presents the description of the data analysis used in this study, by applying the Rasch measurement model to meet the objective. In addition, by using this measurement model, the importance of calibrating the measurement instruments are also highlighted, which involves separating the misfit raw data through the analysis to ensure statistically more accurate analytical results. Evaluation of the quality of the technical aspects for each of the involved item is very important in the measurement model. The analysis will be able to improve the reliability of the items which could indirectly serve the purpose of calibrating the instrument to ensure a more accurate measurement to produce a meaningful research.
