Document Summary

Measuring/observing 2 variables and looking at the relationship between the two variables. Disadvantages: 3rd confounding variable influencing the relationship, can"t tell the direction of the relationship (a can influence between 2 variables. Over 500,000 ways of retrieving evidence-based info via: We cannot make decisions with the absence of data = biggest: authority ethical issue in medicine. Reduces ambiguity in the interpretation of results. One variable is manipulated and a second variable is. Measured: measuring the effects on the dependent variable. Example: does exercise reduce anxiety: want to manipulate independent variable = exercise. Divide group into 2 separate groups (group that exercises vs. group that does not exercise) If a variable is held constant, it can"t be responsible for the results of the experiment: if constant = can"t be responsible for the results of the. The only difference between groups should be the variable experiments you"re manipulating: ex: diet*, other activities, social interaction, age.
