Abstract: (5330 Views)
To address research questions, measuring variables are neccessary. However, every measurement is prone to different types of measurement errors. Therefore, understanding about the different types of measurement errors are a great of importance This paper presents four types of measurement errors 1) Disagreement, which is discrepancies between the results of two or more than two measuring tools or observers 2) Random error which is a none-directional gap between the true and measured values 3) Systematic error or bias which is a directional gap between the true and measured values, and finally 4) Confounding error which changes the strength of association between dependent and independent variables in analytical studies.
