Weegy: Hi Your ans is c. Determine whether measures will produce consistent scores on multiple occasions Explanation: In statistics, reliability is the consistency of a measure. [ A measure is said to have a high reliability if it produces consistent results under consistent conditions. For example, measurements of people?s height and weight are often extremely reliable. ] User: Which of the following is not a requirement of a true experiment? a. Random assignment b.
