RESEARCH STUDY 5.1: 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 is concerned about the validity of the measure of narcissism recommended by her colleague. She sends a copy of the measure to the faculty members in her psychology department to look at, and they all tell her it looks like it will measure narcissism. She now has evidence of which of the following?
face validity
In the case of a factorial design, another term for independent variable is
factor.
External validity is most important for which of the following claims?
frequency claims
In conducting quasi-experimental designs, researchers tend to give up some ________ in exchange for ________.
internal validity; external validity
A question that suggests a particular viewpoint to respondents is known as a(n)
leading question.
The arithmetic means for each level of an independent variable, averaging over levels of the other independent variable, are called
