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?
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.
