Segmentation lets you ask "how is this group different?" without exporting anything. Pick a dimension — like age, gender, or any choice question — and the entire results dashboard re-calculates for that group and compares it to your overall sample.

When to use it

  • You want to know how a subgroup (e.g. 18–28, or promoters) answers differently from everyone.
  • You're preparing a readout and need the standout differences fast.
  • You want to validate that a segment is large enough to trust.

How to segment

  1. Open a study and go to its results page.
  2. Above the tabs you'll see the Segment by bar. Choose a dimension from the dropdown (any single/multiple-choice, yes/no, rating, NPS, or similar question with a handful of distinct answers).
  3. Click one or more values (e.g. 18-28). The whole dashboard re-segments instantly.
  4. The bar shows how many responses match (e.g. 129 of 1,379 · 9%). Click Clear to reset.

You can combine values within a dimension (OR) and across dimensions (AND) — for example Female and 25–34.

What changes when a segment is active

  • KPI cards show the segment's numbers with a delta versus everyone (e.g. completion rate, average time).
  • Per-question charts switch to a side-by-side comparison: the segment (green) over everyone (gray), with the point difference per answer.
  • The Notable differences panel appears at the top of the Overview tab — see Notable differences.
  • The question you segmented by is excluded from the comparison (so you don't see the tautology "the 18–28 group is more likely to be 18–28").

Tips & best practices

  • Aim for at least ~20 responses in a segment before reading too much into differences — small samples are noisy. SegmentOS labels low-sample insights as "early signal."
  • Use segmentation alongside the Drivers tab to go from "who differs" to "what predicts the outcome."
  • Everything is calculated in your browser, so it's instant and private.
