PLEASE SOMEONE GIVE ME A LEGIT ANSWER in the following experiment (with Dan), identify the errors that the experimenter made and summarize a valid way to test his research question
What cooking spray best keeps food from sticking to a pan? In the morning, Dan uses grapeseed oil to cook eggs for breakfast; for lunch, he uses vegetable oil spray to coat a muffin try and cooks cornbread to eat with his chili; and for dinner, he uses olive oil to pan cook a hamburger patty.
