Why is replication important to consider when designing an experiment?

      The main reason behind the importance of replication in science is that, when you design an experiment, you're seeking for something called constancy, and in science, this is very important because variability can ruin  your experiment, or make it harder.

        With replication, there are less chances of a big variability to happen, and by that, your experiment is balanced enough in a way that will make the data you collect, easier to analyse and get to a conclusion. One of the main things you need to consider when designing an experiment is how you'll analyse the data you'll get, and what you'll do with it for your next step.
