Can a research instrument be reliable but valid?

To be legitimate, an instrument must be dependable. An instrument must constantly deliver the same score in order to be considered genuine. An instrument, on the other hand, may be dependable but not valid: it may consistently provide the same result, but the result may not reflect a person's real performance on the variable.

When choosing a survey instrument, reliability and validity are crucial considerations. The instrument's reliability relates to how consistently it produces the same findings throughout repeated trials. The degree to which an instrument measures what it was supposed to measure is referred to as validity.

For example, if your scale is wrong by 5 pounds, it will reflect your weight incorrectly every day. The scale is trustworthy since it gives the same weight every day, but it isn't accurate because it adds 5 pounds to your actual weight. It isn't a reliable indicator of your weight.
