question

question

question
If Dr. Fletcher is interested in a causal relationship between joining a fraternity/sorority and attractiveness/appearance concern, why doesn't he conduct a true experiment?
answer
He was unable to randomly assign participants to join a fraternity/sorority.
question
In addition to measuring the group of participants who joined a fraternity/sorority, Dr. Fletcher decides to give the same measure to another group of 55 participants who decided to not join a fraternity/sorority. Doing this would help Dr. Fletcher address all of the following threats to internal validity EXCEPT:
answer
Experimenter Bias
question
Which of the following is NOT an advantage of using quasi-experimental designs?
answer
They allow researchers to disregard internal validity.
question
Why do quasi-experiments tend to have very good construct validity for the independent variable?
answer
They use real-world manipulations/experiences.
question
n which of the following ways are correlational designs similar to quasi-experimental designs?
answer
They both suffer from possible threats to internal validity.
question
Which of the following is true of the difference between large-N experiments and small-N experiments?
answer
Each person in a small-N design is treated as a separate experiment
question
Seeing stability in a stable-baseline design can help rule out which of the following threats to internal validity?
answer
Regression to the mean
question
What type of small-N design has Dr. Anderson used with W. J.?
answer
Multiple-baseline design
question
Dr. Natchez, a colleague of Dr. Anderson, questions whether W. J. simply wrote down less in his journal as the study went on because he grew tired of completing this "measure." Dr. Natchez believes he has uncovered which of the following threats to internal validity?

question
If a researcher is concerned about external validity, which of the following would you recommend with regard to conducting small-N designs?
answer

answer
A weaker causal claim than a true experiment
question
Which of the following people would be of most interest for a small-N design?
answer
