Reliability
An instructor conducted an experiment to determine the effects of two different methods of study on the amount students learned in introductory physics. The results showed that the average amount learned by the group using one method was greater than the average amount learned by the group using the other. However, the difference was not statistically significant. Which of the following is the most appropriate conclusion to be drawn?
There is a possibility that the difference between the two groups occurred by chance.
Operational definitions are used for which of the following reasons?
They enable researchers to replicate studies by precisley decribing the variables and how they are used.
The next questions refer to the situation described below. In an experiment designed to determine whether watching violent scenes on television increases the frequency of aggressive behavior in children, one group of subjects saw a nonviolent cartoon and another group saw a violent cartoon. In the play period that followed the viewing of the cartoons, researchers observed the two groups of children together and counted instances of aggressive behavior. The dependent variable in the experiment is the
amount of aggressive behavior exhibited by the children.
Which of the following is the strongest correlation?

According to one theory of psychology, many people have mental illnesses because their maladaptive behaviors have proven rewarding for them in the past and thus have been continued. This belief is consistent with which of the following models?
Behavioral
In which of the following types of research are the same children tested periodically at different points in their development

Scatterplot
A research design involves two randomly assigned groups of participants. One group receives a one-time treatment, and the other does not. Later, the two groups are compared to see whether the treatment had an effect. Psychologists call this kind of research
a experiment
Ethical principles developed by the American Psychological Association help ensure that human participants in psychological research

A study can be regarded as scientific only if
its conclusions can be verified or refuted by subsequent studies
A disadvantage of longitudinal studies is that
participants who drop out during the course of the study may be different in important ways from ones who do not drop out

The next questions refer to the situation described below. In an experiment designed to determine whether watching violent scenes on television increases the frequency of aggressive behavior in children, one group of subjects saw a nonviolent cartoon and another group saw a violent cartoon. In the play period that followed the viewing of the cartoons, researchers observed the two groups of children together and counted instances of aggressive behavior. The control group in the experiment is the group that
watched the nonviolent cartoon
