Whilst the validity and reliability of the questionnaire was established through a rigorous three-stage process, limitations should also be noted. whether repeating the measurement yields consistent results. The process of a measure, a tool, or an instrument's quality assessment involves investigating their reliability and validity. If the test is doubled to include 10 items, the new reliability estimate would be It refers to the extent of applicability of the concept to the real world instead of a experimental setup. A common measurement of this type of validity is the correlation coefficient between two measures. Measurement validity and reliability 1. In this sense, the involvement of the researchers in the research process would greatly reduce the validity of a test. whether repeating the measurement yields consistent results. Validity implies the extent to which the research instrument measures, what it is intended to measure. There are several important principles. Because the measurements were all made by one observer, the reliability may be referred to as intraobserver reliability. • Reliability of a measure refers to the extent to which the measurement process is free from random errors. To help distinguish between instrument and instrumentation, consider that the instrument is the device and instrumentation is the course of action (the process of developing, testing, and using the device). Perhaps the most straightforward way to assess reliability is to ensure that they meet the following three criteria of reliability. Reliability; Meaning: Validity implies the extent to which the research instrument measures, what it is intended to measure.
