Edit a metric

  • Updated
  • Optimizely Web Experimentation

After you create a metric in Optimizely Web Experimentation, you can edit it from either the Metrics or Experiment Results page to change its name, winning direction, or measurement.

Edit metrics on the Metrics page

  1. On the Experiments page, select the experiment whose metrics you want to change.
  2. Click Metrics.
  3. Expand Actions and select Edit for the metric you want to change.
  4. Edit the metric as desired.
  5. Click Save to Experiment.
  6. Click Save.

Edit metrics on the Experiment Results page

  1. On the Experiments page, click Results for the experiment whose metrics you want to change.
  2. Click Edit.
  3. Click Metrics.
  4. Expand Actions and select Edit for the metric you want to change.
  5. Edit the metric as desired.
  6. Click Save to Experiment.
  7. Click Save.
Be careful when editing a metric on a running experiment or campaign. Doing so can change the statistical significance on other metrics in the same experiment or campaign. This is because the Stats Engine simultaneously limits the proportion of false detection across all metrics in an experiment or campaign through false discovery rate control.

False discovery control

Optimizely Web Experimentation balances confidence and speed of results by controlling false discoveries only for metrics currently included on the Experiment Results page, adapting as the metrics themselves change.

This means experiments and campaigns with metrics selected and fixed in advanced are less prone to cherry-picked results that may present a misleading picture. Excessive metric changes after an experiment or campaign has started may invalidate Optimizely Web Experimentation's guarantees regarding false detection.
