Imagine that you are collaborating with another researcher on a project. In your experiment, an initial sample of 40 participants randomly assigned to one of two groups (n=20 each) leads to an independent samples t-test result that doesn't quite reach statistical significance (p .08, which is so sad). Your collaborator proposes that you continue the experiment, adding 40 more participants (20 to each condition). Then, your collaborator reasons that, if p is lower than .05, you can publish your final sample size of n=80 with statistically significant results.
