What it shows

  • Pre-calculate sample size and minimum run time before serving variant traffic.
  • Never terminate an experiment before reaching predetermined sample power.
  • Document negative and neutral test findings to prevent testing duplicate ideas.

The takeaway

Lock your sample size upfront and only roll out variants that achieve verified statistical significance.
