Which of the following are reasons for performing experiments? to establish a cause-and-effect relationship between the treatment and the response to overcome ethical difficulties that observational studies could potentially present to measure variables of interest without influencing the responses to identify the effects of a lurking variable on the response variable to determine if a particular treatment has a desired effect on the response variable

Question
**Reasons for Performing Experiments**

When considering the reasons for conducting experiments, the following points are typically emphasized:

1. **Establishing a Cause-and-Effect Relationship**
   - Purpose: To demonstrate a causative link between the treatment administered in an experiment and the subsequent response observed.

2. **Overcoming Ethical Difficulties**
   - Purpose: To address ethical challenges that might arise in observational studies, making it essential to use experimental methods.

3. **Measuring Variables of Interest**
   - Purpose: To assess specific variables of interest systematically, without manipulating or influencing responses in a natural setting.

4. **Identifying Effects of Lurking Variables**
   - Purpose: To detect and understand how an unobserved variable (lurking variable) might affect the relationship between the treatment and response.

5. **Determining Treatment Effectiveness**
   - Purpose: To evaluate whether a specific treatment produces the desired outcome on the response variable.

This content provides foundational understanding for educators and students on the objectives behind performing experimental research in scientific and social sciences. Additionally, exploring hypotheses and validating results are crucial components of experimental design.
