Document Summary
Chapter 8: control: the keystone of the experimental method. Results are influenced by chance: null hypothesis. Each group is drawn from the same population and the effects of the conditions are not different from one another: confound hypothesis. Results are influenced by a factor other than the independent variable: research hypothesis. Results are related to the independent variable. Through control and manipulation, participant variables may be examined in detail: the influence on variable has on another is made certain. Emphasize control in three ways: control as related to the participant assignment, related to experimental design, related to the logic of experimentation. Some reports that say sex differences exist and some say that they do not. In the study, the researcher would not necessarily know if the results are due to sex differences or to the variable being studied o. Convenience sampling affects the external validity of the study. Random sampling can be accomplished: random number table.
