(A) reliability
Spoiler
Explanation
Karthik and Sue’s way of measuring friendliness is not reliable. Reliability refers to the
consistency of a measure. Since they disagree so often, their measure is not consistent. In all likelihood, they need to operationalize their dependent variable more clearly. Reliability is sometimes confused with validity. Validity refers to the accuracy of a measure, which in this case is whether they are actually measuring friendliness.
