The following are the characteristics of True Experimental Research Design; EXCEPT:
Appeared in: AIIMS Raipur lecturer 2021
Explanation
- Assumption is the correct answer as it is not considered one of the three core, defining characteristics of a true experimental design.
- While researchers make assumptions in any study (e.g., assuming participants will answer honestly), it is not a structural component of the design itself.
- The three essential properties that define a true experimental design are Manipulation, Control, and Randomization.
Why Other Options Were Wrong
- Option B: Control is a fundamental characteristic of a true experimental design. It involves using a control group to provide a baseline for comparison and to rule out the influence of extraneous variables.
- Option C: Manipulation is a core feature of a true experimental design. It refers to the researcher actively introducing an intervention or treatment (the independent variable) to see its effect on an outcome.
- Option D: Randomization is an essential property of a true experimental design. It involves randomly assigning participants to either the experimental or control group to eliminate selection bias and ensure the groups are comparable from the outset.

Clinical Relevance
- Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Characteristics of True Experimental Research Design as background academic context rather than a clinical decision trigger.
- Understanding research designs is crucial for nurses to practice evidence-based care. It allows them to critically appraise research studies like Randomized Controlled Trials (RCTs) and determine if the findings are valid and applicable to their patients.
- By identifying high-quality evidence from well-designed studies, nurses can support changes in clinical protocols that lead to improved patient safety and outcomes.
- What if a study has manipulation and control but lacks randomization? The design is then considered 'quasi-experimental,' not a 'true' experiment. This is a weaker design because the groups may not be equivalent at the start, which introduces a higher risk of bias in the results.
How to Approach the Question
- First, identify the core subject of the question, which is 'True Experimental Research Design'.
- Next, notice the keyword 'EXCEPT'. This signals that you must find the option that does NOT belong.
- Recall the three defining characteristics of a true experimental design. A helpful mnemonic is 'MCR' (Manipulation, Control, Randomization).
- Evaluate each option against these three characteristics.
- Control, Manipulation, and Randomization are the core characteristics.
- 'Assumption' is the only option that is not part of this defining trio, making it the correct answer.
Concept Tested & Keywords
- Concept Tested: Characteristics of True Experimental Research Design
- Stem keywords: True Experimental Research Design, characteristics
- Lead-in keywords: EXCEPT
- Negative lead-in flag: The question asks to identify the option that is NOT a characteristic of a True Experimental Research Design.
