Question 3

An educational psychologist is testing the discriminant validity of a new measure of numerical learning difficulties. He gives his measure to a group of students along with another measure of verbal learning difficulties, which he predicts should not be strongly related to numerical learning difficulties. Which of the following correlations would the psychologist hope to find in order to establish discriminant validity?

Accepted Answer

A) r = 1.0 
B) r = −1.0 
C) r = 0.83 
D) r = −0.18 
A) r = 1.0 
B) r = −1.0 
C) r = 0.83 
D) r = −0.18

Question 4

Which of the following is NOT an example of physiological measurement?

Accepted Answer

A) Measurements of hormones in the bloodstream 
B) Blood pressure measurements 
C) Number of panic attacks a patient reports 
D) A brain scan made using an fMRI

Question 5

Dr. Rodriquez is considering conducting a study examining whether narcissistic people have poorer romantic relationships than those who are not narcissistic. One of her first tasks is to determine which of her participants are narcissistic and which are not. She decides to use the scale created by a colleague, the Donal scale. Question 1 reads, "I tend not to think about other people as much as I think about myself." Question 2 reads, "I do not have a high opinion of myself." Question 3 reads, "I think other people think I am really special."
Dr) Rodriquez calculates a correlation coefficient (r) to examine the relationship between Question 1 and Question 2 and between Question 1 and Question 3. She finds a correlation coefficient of r = −0.73 between Questions 1 and 2 and a correlation coefficient of r = 0.74 between Questions 1 and 3. Which of the following is true of her findings?

Accepted Answer

A) There appears to be good internal reliability in the scale. 
B) The correlation between Questions 1 and 2 and Questions 1 and 3 are in the same direction. 
C) The correlation between Questions 1 and 2 is much weaker than between Questions 1 and 3. 
D) The negative correlation between Questions 1 and 2 is bad for Dr. Rodriquez.
