Explanation

If you make a copy of something, like a form or a picture, you have made a replication of it. You might need to mail in a replication of your tax forms when you apply for college financial aid. When you conduct an experiment, you have to repeat it several times to verify that your hypothesis is correct. Each repetition is one replication.
