How do we know if the instrument is good?
An instrument must be reliable in order
to be valid. For an instrument to be valid, it must consistently give the same score. However, an instrument may be reliable but not valid: it may consistently give the same score, but the score might not reflect a person’s actual score on the variable.

What are the types of research instruments?
A research instrument can include
interviews, tests, surveys, or checklists
. The Research Instrument is usually determined by researcher and is tied to the study methodology. This document offers some examples of research instruments and study methods.
What is reliability of instrument?
Reliability refers to
the extent that the instrument yields the same results over multiple trials
. Validity refers to the extent that the instrument measures what it was designed to measure.
What will happen if research instruments are not prepared?

. Research means detailed study of an object. So if the research lacks of detail, your readers will not be interested on reading it. And if your readers are not interested, they will leave a bad feedback on your work.
Why is it important to consider the validity and reliability of your research instrument?
The purpose of establishing reliability and validity in research is
essentially to ensure that data are sound and replicable, and the results are accurate
. The evidence of validity and reliability are prerequisites to assure the integrity and quality of a measurement instrument [Kimberlin & Winterstein, 2008].

When can we say that the instrument is valid?
Part II: Validity
Validity is
the extent to which an instrument measures what it is supposed to measure and performs as it is designed to perform
. It is rare, if nearly impossible, that an instrument be 100% valid, so validity is generally measured in degrees.
What is validity in quantitative research?
Validity is defined as
the extent to which a concept is accurately measured in a quantitative study
. … The second measure of quality in a quantitative study is reliability, or the accuracy of an instrument.
