Validity refers to the extent to which a measurement tool or instrument actually measures the construct or concept it is intended to measure. It is a measure of the accuracy or relevancy of the measurement in relation to the theoretical concept it is supposed to measure. Reliability refers to the consistency of the measurement, while internal consistency refers to the degree of coherence or correlation between different components of a measurement tool. Randomization refers to the process of randomly assigning participants to different groups in a study. None of these terms directly relate to the accuracy or relevancy of measurement for a given construct or concept.
