Psychometric reliability9/9/2023 ![]() Differing and widely spread marks will cause low variability for the tasks. Since each essay asks a different question and in that way evaluates alternative student abilities, the results will vary across one measurement scale. The variability of the hypothetical assessment is another key element to consider. However, that would be difficult considering how different they are compared to each other. Hence, improving reliability would require each question to be assessed according to similar criteria (Clayson & Miller). Furthermore, in this case, the probability of random error is high the exemplar questions differ significantly based on their content and format. The hypothetical essay writing is not based on previously conducted studies with empirical support. Researchers often increase their sample and repeat the procedure multiple times to purify the scale and improve the psychometric reliability (Quoquab et al., 2019). ![]() Focusing on the reliability factor, the task’s scale and procedure must be discussed. The hypothetical assessment instructs students to write an essay in two days. In that way, the hypothetical test questions must be analyzed to highlight their possible ineffectiveness. ![]() Moreover, psychometric assessments must have clear and comprehensible instructions and purpose. ![]()
