Mike takes his temperature with a thermometer three times over a 20 minute period and observes the following measurements: 98, 106, and 89 degrees. In this context, Mike concludes that the _____ of the thermometer is _____.A. validity; highB. variability; lowC. reliability; lowD. reactivity; high64. A researcher conducts an experiment to establish a relationship between a chess player's mental stability and his performance in a game. He finds that the two have a Pearson product-moment correlation coefficient value of +1.00. This means the two variables—mental stability and performance—have a _____ relationship.
