Reliability will reflect whether the measured height of the child is consistent. The most direct way to measure the height of a child is to get a tape measure and measure the child from head to foot.

Here, height is the key variable under study, and we need to develop an instrument to measure a person's height. Overview of ReliabilityĪgain, reliability answers the question, 'How consistent is the instrument?' Imagine we are measuring a person's height. The different types of reliability evidence are described below. Briefly, reliability is the degree to which the instrument is consistent whereas validity is the how well the instrument measures what it is supposed to measure. Reliability and validity are the two ways that researchers evaluate the quality of an instrument. Not all instruments are created equally - some are good instruments, some are bad instruments, and others are mediocre. Once an instrument has been developed, the reliability and validity of the instrument needs to be evaluated.
