Question

A psychology professor wants to test the effectiveness of providing students in his introductory experimental psychology class with an outline with his weekly lecture notes. He forms two groups within his class, each containing 24 students. The experimental group receives an outline of the professor’s weekly lectures, and the control group receives no outline. Grades at the end of the semester are compared between the two groups. On the basis of this description, discuss what flaw is most evident in the design of the experiment. Identify and design and discuss an alternative procedure that might eliminate the flaws.

class with an outline with his weekly lecture notes. He forms two
groups within his class, each containing 24 students. The
experimental group receives an outline of the professor’s weekly
lectures, and the control group receives no outline. Grades at the

One Management professor adopted a crossword puzzle exercise in
his introductory management information systems (MIS) class,
because he believes that the most important effects of engaging in
a crossword exercise is the great workout it gives one's
brain—solving crossword puzzles requires several skills, such as
spelling, reasoning, making inferences, evaluating choices, and
drawing conclusions. That is, the exercise may enhance one's
ability to memorize words. He wants to know whether or not the
crossword puzzle exercise can accelerate the learning...

I need assistance with this question:
A psychology professor is interested in whether implementing
weekly quizzes improves student learning. She decides to use the
weekly quizzes in one section of her introductory psychology class
and not use them in another section of the same course. Which type
of quasi-experimental design do you recommend for this study?
I understand that it should be the non-equivalent control group
design, because the groups are not randomly assigned, and there is
a treatment group...

In a large introductory statistics lecture hall, the professor
reports that 52% of the students enrolled have never taken a
calculus course, 33% have taken only one semester of calculus,
and the rest have taken two or more semesters of calculus. The
professor randomly assigns students to groups of three to work on a
project for the course. You are assigned to be part of a group.
What is the probability that of your other two groupmates,
a) neither has...

Professor Meanie’s persistent rate (i.e. students who do not
drop the course) is historically 65%. However, this semester he
decided to “flip” his classroom. Instead of coming to class for a
typical lecture, students are expected to watch the lecture online
the night before. The next day students will work in groups of
three on exercises that reinforce concepts from the video lectures.
He started with 120 students and 72 completed the course. Ideally,
he is trying to increase the...

A psychology professor is interested on how different study
techniques affect students’ test performance. He required half of
the class to study the material in 10 sessions of 1 hour each
(i.e., distributed study) while the other half studied it
in 1 session of 10 hours on the same day as the 10th session of the
distributed-study group (i.e., crammed study). Five days
after the last study session for both groups, he tested the
students on the material. He expected...

read the following descriptions of hypothetical studies.
Explain whether each is an experiment, non-experiment, or
quasi-experiment and state why for identifying, and for
explanation).
1. A coach at a high school wants to examine if reduced practice
for athletes caused higher grades. She puts all of the athletes
with low grades into the experimental group and reduces their
practice time from 2 hours to 1 hour. She puts all of the
high-achieving athletes in the control group and keeps their...
