Suppose we are studying the effect of diet on height ofchildren, and we have two diets to compare: diet A (a well-balanceddiet with lots of broccoli) and diet B (a diet rich in potato chipsand candy bars). We wish to find the diet that helps children growfaster. We have decided to use 20 children in the experiment, andwe are contemplating the following methods for matching childrenwith diets: i. Let them choose. ii. Take the first 10 for A, thesecond 10 for B. iii. Alternate A, B, A, B. iv. Toss a coin foreach child in the study: heads?A, tails?B. v. Get 20 children;choose 10 at random for A, the rest for B. Describe the benefitsand risks of using these five methods
