Question

how do i turn the following into something that will give me a month of data? "how does caffeine affect the human body blood pressure and heart rate?" i was going to give coffee to participants and measure their vitals before and after (the coffee portion is a lot more complicated) but i found out i need a month of data and i really don't have time to change my project. please help me this project counts for a third of my grade

Answer 1

You could tell each of the participants to drink a certain amount of coffee (for example: person one drinks 5 oz., person two drinks 7 oz., etc). Then, survey the participants/measure their vitals once every week for a month (or every day if needed) and report about your findings.
