Test whether a phishing click rate really fell

Why it matters

Phishing simulations produce one headline number, the click rate, and every quarter someone reports whether it went down. NIST SP 800-50 Rev. 1 expects a learning program to measure whether it works, and a falling click rate is the usual evidence. A drop of a couple of percentage points across campaigns of a few hundred people is often just chance, and treating it as proof leads to bad decisions: celebrating a program that did nothing, or cutting one that works because a quarter looked worse. A second trap is that click rates depend heavily on how convincing the lure was, so an easier email…

What you'll learn

Steps in this lab

  1. A click rate is a sample proportion
  2. Four campaigns
  3. Write the test
  4. Run it: not proven, then proven but confounded
  5. Report it so it means something
