The extent to which the results can be reproduced when the research is repeated under the same conditions. It’s important to consider reliability and validity when you are creating your research design, planning your methods, and writing up your results, especially in quantitative research.
Reliability is about the consistency of a measure, and validity is about the accuracy of a measure. They indicate how well a method, technique, or test measures something. Reliability and validity are concepts used to evaluate the quality of research.

Probability vs non-probability sampling.It refers to the measuring procedure rather than to the attribute being measured. Reliability: A measure of how dependably an observation is exactly the same when repeated. Lack of validity is referred to as ‘Bias‘ or ‘systematic error‘. Internal validity: Are the results valid for the study subjects?Įxternal validity (Generalizability): Are the results valid for the population from which the sample was drawn? Simply put: Are the values describing what was supposed to be measured?
Validity: The extent to which the study measures what it is intended to measure. Lack of precision is referred to as ‘random error‘. Simply put: How close the measurements are to each other Precision: The degree of resemblance among study results, were the study to be repeated under similar circumstances.
Simply put: How close a measurement is to the true value Accuracy: The degree to which a measurement represents the true value of something.
