Statistics Overview
Statistics turns slice-level Results into comparisons across animals, groups, conditions, brain regions, and stainings.
Use Statistics after the underlying Results look trustworthy.
What Statistics is for
Statistics helps answer study-level questions such as:
- Which groups differ in a selected region?
- Does one staining show a stronger regional pattern than another?
- Are differences driven by counts, proportions, or density?
- How do patterns look across anatomy?
Before calculating statistics
Make sure that:
- staining and model selections are correct
- slice-level output looks reasonable in Results
- selected brain regions are appropriate for the question
For registered projects, make sure processing and registration are complete enough for interpretation.
For Detail only projects, make sure slice brain-region assignments and pixel size are correct before interpreting density or region-level summaries.
Metrics depend on source kind
For shared cell detection projects, Statistics can use total cells, ON cells, OFF cells, % ON, and density metrics.
For independent marker detection projects, Statistics uses accepted marker-positive cells, area, and marker-positive cells/mm2.
Independent marker detection projects do not support % ON or all-cell density because there is no shared all-cell denominator.
Recalculate after analysis changes
If the underlying model, registration, slice inclusion, selected regions, or direct brain-region assignment changes, previously calculated summaries may no longer reflect the current project state.
Recalculate statistics after meaningful changes.
Plot families
Statistics supports:
- Heatmaps for broad animal-by-region pattern scans
- Bar plots for group mean summaries and variability
- Dot/strip plots for individual animal values
- Box/violin plots for distribution shape, spread, and medians
- Effect-size plots for standardized group differences against a baseline
- Scatter plots for relationships between two selected metrics
- Mirrored plots for side-by-side comparison of two metrics
- Anatomical representations for mapping values back onto brain regions
Choose the metric and plot type based on the biological question.
