1. Relaxation techniques.
2. Relaxation techniques use.
3. Postoperative status.
4. Postoperative pain perception.
2
Rationale 1: "Relaxation techniques" is incorrect because it fails to completely indicate the variable that the researcher seeks to manipulate in terms of using or not using.
Rationale 2: "Relaxation techniques use" is correct because it is the variable that the researcher can manipulate.
Rationale 3: "Postoperative status" is incorrect because it is a descriptor of the population the researcher seeks to study, not a variable.
Rationale 4: "Pain perception" is incorrect because it describes the variable that the researcher seeks to influence. This is the dependent variable, not the independent variable.
