questions with correct answers
Which of the following designs best eliminates differences between
| | | | | | | | |
experimental and control groups? | | |
A)
Johnny conducted a within-participants experiment where he
| | | | | | |
intentionally assigned male participants to the control condition and
| | | | | | | | |
females to his experimental condition in attempts to rule out differences
| | | | | | | | | |
|within each group.
| |
B)
Kevin conducted a between-participants experiment, where he
| | | | | | |
randomly assigned participants to a condition. They then completed
| | | | | | | | |
both the control and experimental manipulations.
| | | | |
C)
Heather conducted a between-participants experiment where she
| | | | | | |
intentionally assigned male participants to the control condition and
| | | | | | | | |
females to his experimental condition in attempts to rule out differences
| | | | | | | | | |
|within each group.
| |
D)
Laura conducted a within-participants experiment, where each
| | | | | | |
participant completed the control and experimental condition. -
| | | | | | | |
CORRECT ANSWER✔✔-D) |
,Laura conducted a within-participants experiment, where each
| | | | | | |
participant completed the control and experimental condition.
| | | | | |
Natalie created a pill to focus attention. She had a friend take the pill
| | | | | | | | | | | | | |
before writing her Spanish exam. She then had the same friend write
| | | | | | | | | | | |
her calculus exam without taking the pill. Natalie reviewed the test
| | | | | | | | | | |
scores to see whether or not taking the drug increased her friend's
| | | | | | | | | | | |
performance. Which of the following best describes Natalie's
| | | | | | | |
experimental design? |
A)
Using a within-participants design, Natalie has minimalized all possible
| | | | | | | | |
external variables. |
B)
Natalie accurately created a control condition equal to that of the
| | | | | | | | | | |
experimental condition, which will help validate her results.
| | | | | | |
C)
Natalie inaccurately created a control condition, as it did not equal that
| | | | | | | | | | | |
of the experimental condition, discrediting her results.
| | | | | |
D)
Using a between-participants design, Natalie has minimalized all
| | | | | | | |
possible effects external variables. - CORRECT ANSWER✔✔-C)
| | | | | |
Natalie inaccurately created a control condition, as it did not equal that
| | | | | | | | | | | |
of the experimental condition, discrediting her results.
| | | | | |
,You want to measure the athleticism of the average Hamiltonian (a
| | | | | | | | | | |
person who lives in Hamilton). When recruiting participants, which of
| | | | | | | | | |
the following is the least favourable strategy?
| | | | | |
A)
Recruiting randomly from various gyms in Hamilton.
| | | | | |
B)
Recruiting people of different ages and gender.
| | | | | |
C)
Recruiting randomly from both the university population and the
| | | | | | | | |
general public. |
D)
Recruiting randomly from various Hamilton locations. - CORRECT
| | | | | | | |
ANSWER✔✔-A)
Recruiting randomly from various gyms in Hamilton.
| | | | | |
Which of the following best describes a method to avoid participant
| | | | | | | | | | |
bias?
A)
Giving the control group a mock treatment, so they are unaware of
| | | | | | | | | | | |
which condition they are in.
| | | |
B)
Explaining the hypothesis prior to the experiment, so participants are
| | | | | | | | | |
aware of potential biases they may have.
| | | | | |
, C)
Exposing the experimental groups to the manipulated variable, so they
| | | | | | | | | |
are aware of which condition they are in.
| | | | | | |
D)
Keeping the experimenter blind to conditions, preventing them from
| | | | | | | | |
influencing participants' performance. - CORRECT ANSWER✔✔-A)
| | | | |
Giving the control group a mock treatment, so they are unaware of
| | | | | | | | | | | |

| | | |
Which of the following values indicates the strongest relation between
| | | | | | | | | |
two variables?
|
A)
r = 1.01
| |
B)
r = -0.8
| |
