Question 2

Suppose a woman weighs 130 pounds as measured by an accurate scale in her physician's office. Also suppose that her scale at home gives the following readings over a 5-day period: 126, 134, 128, 132, 130, so the average is an accurate 130 . Assume that her actual weight has not varied during the five days. Does her scale give reliable measurements? Does her scale give valid measurements? Explain in both cases.
 
  What will be an ideal response?

Answer to Question 1

Answer to Question 2

The scale is neither reliable nor valid. It is unreliable, since it gives inconsistent measurements, and even though the average is an accurate 130, the measurements cannot be valid, since they're unreliable.
