Tutorial Methods on How to Test the Observation Techniques’ Validity and Reliability in Social Science and Applied Research

Abstract

This study is presented as a set of guiding methods intended to assist researchers in applying validity and reliability testing procedures systematically. It provides an in-depth examination of observation techniques and procedures used in the social sciences and applied research, with a particular focus on how their validity and reliability can be verified. Unlike many previous studies, this review offers a clear methodological framework for evaluating the accuracy of data extraction, supported by the use of precise and reliable tools and techniques designed to meet the needs of novice researchers. The study emphasizes the fundamental methods required for constructing observation instruments, designing reliability tests, and analyzing and interpreting results, in addition to applying these procedures in real research contexts. The findings indicate that strict adherence to these steps contributes significantly to enhancing the validity and reliability of data derived from observation. This study seeks to bridge the gap between theory and practice by providing accurate and sound observation methods grounded in solid scientific principles within research environments.
