Research hypotheses may be simple or complex. Which statement describes a study that is designed to test a complex hypothesis?
1. Two groups of subjects are in the study.
2. More than two variables are to be tested in the hypothesis.
3. Complex definitions for the variables are in the hypothesis.
4. The hypothesis will be too difficult to test in a study.
2
Rationale 1: The number of groups in a study is not 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.
