Analysis & results

Open a study and go to its results to explore how participants sorted. All analysis is computed live in your browser, so sliders and filters update instantly.

Overview & filters

The top of the results view shows: how many participants are in the current view, how many are quality-flagged (suspect/rejected), the median sort time, and the average number of groups per participant.

Two filters control everything below them:

Include flags: toggle ok / suspect / rejected responses in or out of the analysis. Low-effort responses can be excluded with a click.
Segment: narrow analysis to people who chose a particular screener answer (single/multiple-choice questions), to compare segments.

Filters are live-only: they reset on reload and don't change your data.

Similarity matrix

A card-by-card heatmap. The darker a cell, the more often those two cards were placed in the same group. Cards are ordered by clustering so related cards sit together. Hover any cell for the exact pairing and percentage. Export it as CSV.

Dendrogram (clustering tree)

Shows how cards merge into groups, from individual cards up to the whole set.

Cluster slider: one slider sets how many groups to split into, from 1 (everything together) up to one group per card. As you drag it, a live average within-group agreement % updates so you can see how tightly the cards cohere at each number of groups (it climbs as you add more, smaller groups). This count is shared with the 3D view and Suggested groups.
Linkage method: Average agreement (the default; balanced) or Strongest pair (single-linkage; useful with smaller samples).
A legend lists each cluster's color, your saved name, and its cards.

3D cluster view

The same clustering shown as an interactive 3D scatter of the cards: drag to rotate, scroll to zoom, click a point to focus a cluster. A sidebar lists clusters by name and card count, and you can name groups with Graham here too.

Suggested groups

The dendrogram cut into your chosen number of groups, shown as editable cards. Each group shows its cards, a within-group agreement % (green ≥60%, amber 30 to 60%, red <30%), and the labels participants actually used for it. Rename any group inline. Names are saved by the set of cards in the group, so a group keeps its name as you adjust the slider, and the name is shared across the dendrogram, 3D view, and report. Click Have Graham name groups and in one pass he gives every group a short, distinct name and a one-line description of what it is about, both saved with the group and shown beneath its name. Each group gets its own name, so you never see two groups labelled the same. On paid plans you can also download the groups as CSV/Excel. These named, described groups are what you can port straight into a pairwise project (see the pairwise article).

Popular placements

For closed/hybrid sorts (and standardized open sorts): a card × category table showing how many participants put each card in each category, with a "times sorted" total per card. Darker means more agreement. Up to 14 categories shown; export as CSV.

Standardizing created names (open/hybrid)

Participants invent their own group names, so you'll see many variations of the same idea. The standardization grid lists every raw name with how often it was used and its quality flag, and lets you map them to a single standardized name. Standardizing rolls those responses together everywhere else (popular placements, clustering, report).

Participant management

See each response individually: effort flag and reasons (e.g. "fast response," "left in presented order," "questionable category names," "too few groups," "most cards in one pile," "under the minimum time"), duration, and the groups they made. The few-groups, giant-pile and minimum-time checks are driven by the study's Response quality settings.

Replay a sort as a timeline (where movement data was captured).
Export one participant's data as JSON (for data-subject requests).
Delete a response: permanent, and it's removed from all charts and counts immediately.
