In an experiment to find out if taking ginseng increases IQ scores, the IQ scores would be the independent variable. a control variable. an extraneous variable. the dependent variable. Which of the following is considered a disadvantage of naturalistic observation? It provides an overabundance of information. It deals with behavior not tampered with by outside influences. It limits biased observation through careful record keeping. It does not identify the cause of observed behavior. Subjects are said to be assigned randomly when they are assigned to experimental and control groups from a sample which is representative of the larger population. they each have an equal chance of being assigned to either the experimental or control group. they are assigned to experimental and control groups so that the groups differ on some critical variable before the experiment begins. neither the experimenter nor the subject knows whether the subject is in the experimental or control group. An experiment is performed to see if background music improves learning. Two groups study the same material, one while listening to music and another without music. The independent variable is learning. the size of the group. the material studied. music. The chief function of the control group in an experiment is that it allows mathematical relationships to be established. provides a point of reference against which the behavior of the experimental group can be compared. balances the experiment to eliminate all extraneous variables. is not really necessary. Students who do better in high school tend to do better in college. This is an example of a negative correlation. a zero correlation. a positive correlation. a perfect correlation. In the traditional learning experiment, the effect of practice on performance is investigated. Performance is the _____________ variable. independent extraneous dependent
