How many replicates do you need to be a statistically sound experiment?

The number of replciates will be really dependant on what type of experiments we; re doing, but it should be at least 2 replicates.

Making replicates in an experiment is really useful to make sure that the data that we collected is correct and not misguided, so we could utilize that data and make the most reliable conclusion as possible

There are differences of acceptance of error in Science and Art courses. In Science, since we are dealing with controllable substances and phenomena, we consider a 1% of error. In Art however, we consider a 5% of error knowing we cannot control emotions and behaviors. However both courses considered at least 3 replications for the experiment to be considered statistically sound.
