A study compared the reduction of typing errors in two groups of typing students, both of which were already advanced typists. One group was paid well for typing accuracy and the other group was given positive verbal feedback. No difference in typing accuracy was found at the end of the study.
What might explain the lack of a treatment effect?

c. confounding treatments |
Homework Answers
Answer:
The correct answer is b. ceiling effect.
The ceiling effect is an effect which takes place when the changes in the independent variable have no visible effect on the dependent variable. So, the correct answer is ceiling effect as it might explain the lack of a treatment effect.

Two researchers conducted a study in which two groups of students were asked to answer 42 trivia questions from a board game. The students in group 1 were asked to spend 5 minutes thinking about what it would mean to be a professor, while the students in group 2 were asked to think about soccer hooligans. These pretest thoughts are a form of priming. The 200 students in group 1 had a mean score of 218 with a standard deviation...

Question 4 (2 points) Saved The study "Transcatheter or Surgical Aortic-Valve Replacement in Intermediate-Risk Patients" was published in the New England Journal of Medicine in 2016. This study compared the efficacy of two treatments for cardiovascular malfunction. Over 1,000 low-risk patients were randomly assigned to a standard treatment: a type of invasive heart surgery. Another 1,000 low-risk patients were randomly assigned to a nonstandard treatment: the use of a less invasive non-surgical catheter. Researchers compared the two treatment groups, and...

A professor predicts that students will lean better if they study to white noise (similar to a fan) compared to music or no sound. She randomly divides 27 students into three groups and sends them to three different rooms. In the first room, students hear white noise, in the second, music from a local radio station, and in the third, the door is closed to help block out normal sound from the hall. Each group is...
