A couple of days ago I was trying to nail down p-value, significance levels and null hypotheses. I know that if the p-value is lower than 0.05, the result is significant and the null hypothesis is rejected – but that’s just memorization. I wanted to understand it, know when it should be applied, and be able to explain it to others. I turned to my trusty co-worker, R., to help in this endeavor. (If you prefer you can skip the dorky “Brianne comes to understand p-values” conversation and go right to the “why this shit is important” section below.)
