1 What type of validity is being assessed in the following example?

The consultant analyzes the correlation between a player’s agility test completion time and the round of the draft in which the player is selected.
2 What type of reliability is being assessed in the following example? A testing company administers an IQ test to a large classroom of middle school students. Each student’s IQ is recorded. The testing company returns a few weeks later and gives the IQ test to the same group of students. The company calculates the similarity between both sets of test scores.
3 What type of reliability is being assessed in the following example? A study will examine the effects of a fever reducing drug in Belgium and the United States. A thermometer that measures temperature with the Fahrenheit scale will be used in the US part of the study and a different thermometer that measures temperature with the Celsius scale will be used in the Belgian part of the study. The research team wants to make sure that error isn’t introduced because they are using different thermometers. Before the study, nurses simultaneously take the temperature of 102 patients with the Celsius thermometer and the Fahrenheit thermometer. A scale conversion is calculated and the measurements from each thermometer are examined to see how closely correlated they are.
