How does an operational definition differ from conceptual definition?
An operational definition specifies the procedures or operations used to measure or observe a concept, making it measurable and testable. A conceptual definition, on the other hand, explains the general meaning or idea behind a concept without providing specific measurement criteria.
Principles of educational measurement?
Educational measurement involves the use of standardized tests, assessments, and other methods to evaluate student learning and performance. The principles include reliability (consistency of measurement), validity (accuracy of measuring what is intended), fairness (lack of bias), and practicality (ease of administration and interpretation). These principles ensure that educational measurements provide meaningful and reliable information for decision-making in education.
What is the definition of unsubstantiated opinion?
An unsubstantiated opinion is a viewpoint or belief that is presented without any evidence, proof, or support to back it up. It lacks credible sources or data to validate its validity or accuracy.
Similarity of reliability and validity?
Reliability and validity are both important concepts in research, but they are not the same. Reliability refers to the consistency and stability of a measurement tool, while validity refers to the accuracy and truthfulness of the conclusions drawn from the data collected. Both concepts are crucial in ensuring the credibility and trustworthiness of research findings.
What is the definition of classroom assessment measurement?
