Final answer:
The true statement about the relationship between reliability and validity is that none of the provided options are true. Reliability refers to consistency of measurement, whereas validity refers to the accuracy of what is being measured.
Step-by-step explanation:
The statement that is true about the relationship between reliability and validity is: D. None of these statements are true. Reliability refers to the consistency of a measure; it means that the same data collection process, when repeated under the same conditions, yields the same results. However, reliability does not guarantee validity. Validity is about accuracy - whether the instrument measures what it is intended to measure. You can have a reliable measure that is not valid if it consistently yields consistent yet inaccurate results. An example is a miscalibrated scale that consistently gives the wrong weight. Conversely, for a measure to be valid, it must also be reliable, because if it gives inconsistent results, you cannot be sure it is accurately measuring what it is meant to.
