the repetition principle is important in scientific research, because the observational indexes are random variables,which requires a certain amount of samples to reveal their changing regularity
repeating something as in a meaning of a word helps us not only remember but have it stuck in our brain. My science teacher in 10th made us rewrite our vocab everyday until all of us knew it. When it came to test taking it was so much easier when I thought of the word. Repetition is so important in science to not only get you to understand the meaning of something but help you remember it.
