113. In order to increase typing speed, Minisoft has redesigned its keyboard and provided a chime that is related to typing speed. The company wants to know if its innovations affect typing speed. Identify the independent and dependent variables in this proposed study.
a) The dependent variable is the chime; the independent variables are the chime and typing speed.
b) The dependent variable is speed of typing; the independent variables are the keyboard design and the chime.
c) The dependent variable is keyboard design; the independent variables are the speed of typing and the chime.
d) The dependent variable is the number of errors made; the independent variables are the chime and the speed of typing.
114. A researcher is investigating the effects of exercise on weight. What are the independent and dependent variables in this experiment?

b) The independent variable is calories consumed; the dependent variable is diet.
c) The independent variable is weight; the dependent variable is calories consumed.
d) The dependent variable is amount of exercise; the independent variable is calories consumed.
115. Dr. Keller has individuals run on a treadmill for 0, 15, or 30 minutes and then measures their self-reported mood. In this hypothetical study, the independent variable is
a) the self-reported mood.
b) the individuals who run for 15 or 30 minutes.
c) the individuals who run for 0 minutes.
d) the number of minutes individuals run on the treadmill.
116. Dr. Proverse has individuals cycle on stationary bikes for 0, 10, 20, or 30 minutes after which he measures their self-reported mood. In this hypothetical study, the dependent variable is _____________.
a) the self-reported mood
b) the individuals who do not ride on the stationary bike
c) the number of minutes individuals ride the bike

117. Ideally, everything in the experimental situation except the __________________ is held constant.
a) inferential statistics
b) placebos
c) independent variables
d) hypotheses
118. Ken is planning on studying the influence of intelligence on the ability to recall events from the 1960s. If Ken does not account for variables such as age that could also influence one’s ability to recall these events, age could be considered a(n) __________________.
a) random variable
b) dependent variable
c) confounding variable
d) independent variable
119. Why is it important to make sure that different participant groups are roughly equivalent in terms of personal characteristics (e.g., age, gender) before any independent variable is introduced?
a) Because it is important to treat all research participants equally so that they feel that they are not being manipulated.
b) Because research ethics forbid any experiment to take place when the participant groups are fundamentally different from each other.
c) So that no major differences between the groups unduly bias the results of the experiment.
d) Because it threatens the integrity of a within-group experimental design.
120. A good control group ________.
a) contains at least one confound
b) has a limited number of dependent variables
c) has a limited number of research participants
d) holds constant all variables in the experiment
