Benefits of Experimental Design
You want to conduct a study to determine whether fruit consumption leads to reduce weight. Why would an experiment be better than an observational study?
An experiment would be better than an observational study for determining if fruit consumption leads to weight reduction because it allows for control over variables, which strengthens the ability to infer causation. Here’s why:
- Controlled Variables: In an experiment, researchers can control for other factors that might influence weight, such as physical activity, calorie intake, or types of fruits consumed. This control reduces confounding variables, making it clearer if fruit consumption itself impacts weight.
- Random Assignment: By randomly assigning participants to either consume fruits or not, an experiment minimizes selection bias and balances unknown factors across groups. This strengthens the reliability of the results, as changes in weight can be more confidently attributed to fruit consumption…
