Measurement

Question 1

To estimate degree of relationship between any 2 given measures, correlation coefficient can be calculated. Correlation should be LOW to show convergent validity and HIGH to show discriminant validity

Answer 1

False

Question 2

Answer 2

Random

Question 3

True score = true measure + random error

Answer 3

True

Question 4

Which is Random error? Systematic error?

• introduces unrepresentative variability, creating noise in data
• presents either positive or negative bias to the average
• traffic noise in study could cause this
• doesn’t affect average value

Answer 4

Random error - introduces unrepresentative variability, creating noise in data
Systematic error - presents either positive or negative bias to the average
Systematic error - traffic noise in study could cause this
Random error- doesn’t affect average value
