I'm doing a science project to see if chewing gum can help improve concentration. How many people should I test
I'm giving the 5 different 1 minute math tests; addition, subtraction, multiplication, division and a mix of all four.
Please DO NOT comment 100 or any other outrageous number. Also do not comment "As many as possible ". I need an exact number before I start this project.
