In a true experimental design, a researcher uses random assignment to
designate two groups: one that receives experimental treatment and one
that does not. - 🧠ANSWER ✔✔True
Quasi-experimental designs are distinguished from true experimental
designs because they lack control groups. - 🧠ANSWER ✔✔False
Laboratory experiments tend to have high external validity, but low internal
validity - 🧠ANSWER ✔✔False
A regression effect occurs when the experimental group performs
consistently better due to being studied. - 🧠ANSWER ✔✔False
In actuality, the experimental effect in the Hawthorne experiment was likely
the result of selection bias. - 🧠ANSWER ✔✔True

,Which of the following is a potential source of internal invalidity that is
associated with the staff of the experiment? - 🧠ANSWER ✔✔Self-fulfilling
Prophecy & Instrument Decay
Between the experimental treatment and the post-test, subjects may drop
out, talk to members of the comparison group, or mature. These are all
problems associated with: - 🧠ANSWER ✔✔Internal Invalidity
While conducting a before-and-after quasi-experiment on fire preparedness
at a local university and before the post-test was administered, a major fire
occurs in a dorm on campus. Although the post-test showed increased fire
preparedness, the researchers could not conclude that their experimental
treatment was the cause. What source of internal invalidity were the
researchers mostly likely concerned about? - 🧠ANSWER ✔✔External
Events
A random distribution of benefits is ethical in experiments when: -
🧠ANSWER ✔✔A researcher does not know if an experimental treatment
will have beneficial effects or if funding does not allow all subjects to
receive treatment
Because staff expectations can change the way that subjects respond to an
experimental treatment, some experiments employ this design in which

,neither the subject nor the staff knows who is getting the experimental
treatment: - 🧠ANSWER ✔✔Double blind Design
To ensure that the treatment is being delivered as planned, many
experiments take periodic measures throughout the experiment. This is
known as: - 🧠ANSWER ✔✔Process Analysis
What experimental or quasi-experimental design contains a pretest, a
treatment, and a posttest, but no control group? - 🧠ANSWER ✔✔Before
and After Design
A researcher studies the effect of admitting men on the performance of
women in traditionally all female colleges. For the study, she selects two
traditionally all-female colleges that are of comparable size, have
comparable admission requirements and costs, and attract a similar type of
student. One of these colleges is soon to begin admitting men. She obtains
academic aptitude scores for all the women in both colleges before the
men were admitted. One year after men are admitted to one college, the
researcher again obtains academic aptitude scores for women at both
colleges. She compares the score for the two colleges to identify the effect
of the college admitting men. The college that did not admit men in this

- 🧠ANSWER ✔✔Non-equivalent control group
By design, a true experiment conducted in a laboratory should be able to
establish all but which of the following criteria for determining that a causal
relation exists between two variables - 🧠ANSWER ✔✔Identification of the
mechanism by which the treatment has its effect
Electronic surveys are a good, inexpensive way to conduct research on the
general population. (142-143) - 🧠ANSWER ✔✔False
