Improving Your Experiment Through Replication
... Statistical precision enables you to accurately characterize gene expression for a particular experimental unit. With adequate replication, you get a more accurate “overall” picture of expression. Without replication, you have more random variation, leading to a less accurate picture and no way to f ...
