Correct Answer:

A scale is any measurement strategy that represents the degree to which a person possesses or manifests a particular variable of interest.So a scale used on a frequent basis by individuals could be a heart rate monitor or even an online stress test that someone completes daily to monitor their level of stress for medical purposes.

Question 2

Correct Answer:

Verified

Convergent validity refers to the degree to which scores on one scale correlate with participants' scores on other measures.This would suggest that these associations make theoretical sense.To have a high degree of discriminant validity,scores should not correlate with measures of unrelated variables.If the scale has both high convergent validity and high discriminant validity then the scale has high construct validity.Two variables that would most likely be associated and possess a high degree of convergent validity based on scale scores would be GPA and SAT scores.Two variables that would be unlikely to share a theoretical association and would possess a high degree of discriminant validity would be psychopathic traits and empathy.

Question 3

Correct Answer:

Verified

Reliability refers to a measure's consistency or stability;validity focuses on accuracy and precision.A useful analogy to understand reliability and validity is to picture a dart board.Someone can throw a dart and repeatedly hit the same wrong spot.In this case,it would be reliable,as it consistently hits the same spot on the dart board,but it would not be valid (accurate)because it does not hit the bull's-eye.
