Rationale 1: The hypothesis tests the relationship between one independent and one dependent variable, so it is simple; but it states the pain level will be different between the groups but does not specify the difference, so it is nondirectional.
Rationale 2: The hypothesis tests the relationship between one independent and one dependent variable, so it is simple, not complex; it states the pain level will be different between the groups but does not specify the difference, so it is nondirectional.
Rationale 3: The hypothesis tests the relationship between one independent and one dependent variable, so it is simple; it states the pain level will be different between the groups, but does not specify the difference, so it is nondirectional.
Rationale 4: The hypothesis tests the relationship between one independent and one dependent variable, so it is simple, not complex; it states the pain level will be different between the groups but does not specify the difference, so it is nondirectional.
