Phukitol is a new anxiety medication undergoing clinical trials. The study is a double-blind random controlled trial (RCT), the gold standard for drug trials. The participants were divided into a Treatment Group which received Phukitol and a Control Group which received a placebo (sugar pill). Neither the doctors nor the patients knew which group they were in during the trial (the meaning of double blind). The trial is now complete and the results have been “unblinded”. The average anxiety level of each individual has been plotted against the side effects that were observed for that individual for all participants. Yellow squares represent individuals that were in the control group, and purple circles represent individuals that were in the treatment group. The paperwork on the participant represented by the red question mark was lost, so we need to figure out which group she was in. Perform a nearest neighbor analysis and kth-nearest-neighbor analysis for k=3, and k=6 to make predictions as to which group the mystery patient was in.
