1 What is typically done to reduce the possibility of selection biases?
a. Choose the sample from a population that is believed to be very
similar
b. Control for the similarity of experimental participants
c. Use random assignment to place participants into differents
experimental condition
d. Add a control group to the experiment - ANS-C Use random assignment to place participants into
differents experimental condition
Professor Pine constructed 2 different short history tests by randomly drawing questions from the
huge pool of all possible questions about the current material. He has created
a. randomly parallel tests.
b. a large sample size.
c. systematic errors.
d. attenuation effects - ANS-A Randomly Parallel Tests
2. Internal validity is best defined as:
a. The extent to which rival hypotheses can explain the findings of an
experiment
b. The extent to which an experiment rules out alternative explanation of
the findings
c. The extent to which the findings are thought to be true of the current
experiment
d. The extent to which the findings can be applied to similar groups of
people - ANS-b. The extent to which an experiment rules out alternative explanation of
the findings
3. External validity is mostly concerned with:
a. The accuracy of experimental hypotheses
b. The importance of applying the findings of experiments to different
samples
c. The generalizability of the findings beyond the setting and sample of
the experiment
d. The validity and appropriateness of using lab research in natural
settings - ANS-C The generalizability of the findings beyond the setting and sample of the
experiment
