Experimental Study: In the experimental study, the researcher would first identify a sample population of individuals who are willing to participate in the study. The participants would be randomly assigned to two groups: intervention vs. control. The intervention group would consume a specific amount of fried food each day, while the control group would not consume any fried food. Both groups would undergo testing to measure cardiovascular health. In this study, the independent variable is fried food consumption, which is measured by recording the amount and type of fried food consumed by the intervention group. Cardiovascular health would be the dependent variable. The research would be conducted as a randomized controlled trial, a type of experimental study. The study could last several weeks or months, and participants would be closely monitored for changes in their cardiovascular health. Following the intervention, both groups would be subjected to post-intervention testing to…
