Research hypotheses may be simple or complex. Which statement describes a study that is designed to test a complex hypothesis?
1. There are two groups of subjects in the study.
2. There are more than two variables to be tested in the hypothesis.
3. There are complex definitions for the variables in the hypothesis.
4. The hypothesis will be too difficult to test in a study.
2
Rationale 1: The number of variables in a study is the determining factor on whether the hypothesis is termed simple or complex.
Rationale 2: A complex hypothesis tests the relationship between more than two variables.
Rationale 3: The complexity of the definitions of variables is not a factor in the hypothesis being termed complex.
Rationale 4: This is not the determining factor in whether a hypothesis is termed simple or complex. If the hypothesis is too difficult to test, the study should be reconsidered or perhaps divided.
