Definitions
- Describing research that involves observing and recording data without manipulating any variables. - Referring to a study that collects data by observing natural phenomena or behavior in its natural setting. - Talking about a method of research that involves collecting data through surveys, interviews, or questionnaires.
- Describing research that involves manipulating variables to observe the effect on the outcome. - Referring to a study that tests a hypothesis by controlling and manipulating variables. - Talking about a method of research that involves collecting data through experiments or trials.
List of Similarities
- 1Both are methods of research used in scientific studies.
- 2Both involve collecting data to analyze and draw conclusions.
- 3Both require careful planning and execution to ensure accuracy and validity.
- 4Both can be used to test hypotheses and theories.
What is the difference?
- 1Methodology: Observational research involves observing and recording data without manipulating variables, while experimental research involves manipulating variables to observe the effect on the outcome.
- 2Control: Experimental research involves controlling variables to isolate the effect of the independent variable, while observational research does not control variables.
- 3Bias: Observational research may be subject to observer bias, while experimental research is designed to minimize bias.
- 4Validity: Experimental research is generally considered more valid than observational research because it allows for greater control over variables.
- 5Applicability: Observational research is often used to generate hypotheses, while experimental research is used to test hypotheses.
Remember this!
Observational and experimental are two methods of research used in scientific studies. The main difference between them is that observational research involves observing and recording data without manipulating variables, while experimental research involves manipulating variables to observe the effect on the outcome. While both methods have their strengths and weaknesses, experimental research is generally considered more valid because it allows for greater control over variables.
