EOM Q1.3.2
Which of the following is an example of observer bias?
a) You develop an opinion of what you expect to see in an experiment.
b) You ask your fellow students to be participants in a study of adult memory.
Consider This: This happens when the person doing the observing has a particular idea about what he or she expects to see. LO 1.6 Compare and contrast some of the methods used to describe behavior.
c) You ask people from your church to participate in a study of family values.
Consider This: This happens when the person doing the observing has a particular idea about what he or she expects to see. LO 1.6 Compare and contrast some of the methods used to describe behavior.
d) You allow a student to quit an experiment simply because he or she is bored.
Consider This: This happens when the person doing the observing has a particular idea about what he or she expects to see. LO 1.6 Compare and contrast some of the methods used to describe behavior.

b) only a small number of subjects need to be accessed.
Consider This: Surveys can be conducted in person in the form of interviews or on the telephone, the Internet, or with a questionnaire. LO 1.6 Compare and contrast some of the methods used to describe behavior.
c) the chance of experimenter error is removed.
Consider This: Surveys can be conducted in person in the form of interviews or on the telephone, the Internet, or with a questionnaire. LO 1.6 Compare and contrast some of the methods used to describe behavior.
d) subjects will not know if they are part of a control or experimental group.

EOM Q1.3.4
Which of the following would indicate the weakest relationship and thus be close to complete randomness?
a) +0.01
b) +1.04
Consider This: The closer the number is to zero, the weaker the relationship becomes. LO 1.7 Explain how researchers use the correlational technique to study relationships between two or more variables.
c) −0.89
Consider This: The closer the number is to zero, the weaker the relationship becomes. LO 1.7 Explain how researchers use the correlational technique to study relationships between two or more variables.
d) −0.98

EOM Q1.3.5
In an experiment to examine the effects of sleep deprivation on completion of a puzzle, one group is allowed to sleep 8 hours while another group is made to stay awake. In this experiment, the control group is
a) the group that gets to sleep.
b) the group that remains awake.
Consider This: The control group is used to control for the possibility that other factors might be causing the effect that is being examined. LO 1.8 Identify the steps involved in designing an experiment.
