P-Value Misuse 101: Spot the Red Flags

P-values are the statistical equivalent of a Rorschach test - everyone sees what they want to see. A 2015 survey of 1,576 researchers found that 51% misinterpret p-values as effect size indicators. Here's how to spot misuse:

  1. *The "Just Below 0.05" Obsession*

    Studies show papers with p=0.049 are 4x more likely to be published than p=0.051. This is called p-hacking.

  1. *The Binary Trap*

    Treating p<0.05 as "true" and p>0.05 as "false" is like saying a 49% chance of rain means it won't rain.

  1. *The Fishing Expedition*

    Running 20 tests and reporting only the significant one? That's like buying 20 lottery tickets and claiming you're rich because one won $5.
