Quizplus · Accepted Answer

The conceptualization of IQ as foot size would lack validity because foot size is not a valid measure of intelligence. Validity refers to whether a measure assesses what it is intended to measure. Foot size and IQ are not related constructs, and thus foot size cannot be used as a valid measure of intelligence. Precision refers to the degree to which measurement is consistent, reliability refers to the degree to which a measure is consistent across time and different conditions, and accuracy refers to the degree to which a measure is true to the actual value or quantity being measured. While IQ tests may vary in their precision, reliability, and accuracy, these issues are not directly relevant to the use of foot size as a measure of intelligence.
