Researchers are intrested to finding out if caffine can affect the radio of formed elements in plasma: A liquid that holds formed elements in blood in suspension.To test this the would form a experiment where several people would give a sample of blood after not comsuming caffine for 24 hours.Then after cumsuming caffine the researchers could then take both samples of blood and spin them in a centrifuge. This will seperate the elements in the blood. The reserchers can collect data by comparing the elements in the plasma. If the elements stay the same the hypotheisis would be proven false. However, if the elements change the experiment should be repeted. If the results stay the same it could be proven that caffine does affect
