# Session Reach/Length by Session Type

Displays box plots comparing session reach and session length for single-session versus multi-session programs.

#### Location

This panel appears on the following dashboards:

* [SNAP-Ed Dashboard](/analyze/impact-dashboards/snap-ed-dashboard.md)

#### Modules Included

* Program Activities

#### Filters

**Applied Filters**

* **Viewable records** — Only Program Activities the current user has permission to view are included.

**Non-Applicable Filters**

All standard Program Activity filters are supported by this panel.

#### Calculations

1. PEARS retrieves all viewable Program Activities that match the current dashboard filters.
2. Programs are classified as single-session (exactly one session) or multi-session (more than one session) based on their occurrence count.
3. For each category, the panel calculates box plot statistics across the sessions of those programs:
   * **Session Length** — Duration of each session in minutes. The box plot shows the minimum, first quartile (Q1), median, third quartile (Q3), and maximum.
   * **Session Reach** — Number of participants per session. The box plot shows the same five statistics.
4. Two box plots are displayed side by side: **Session Reach by Session Type** on the left, measured in reach, and **Session Length by Session Type** on the right, measured in minutes. Each compares single-session and multi-session programs.

#### Additional Notes

* Box plots provide a quick view of the distribution and variability of session metrics.
* The whiskers reach the lowest and highest values in each category, so no points are plotted outside them.
* Sessions with no participant count recorded are excluded from both box plots.
* Sessions are included regardless of their length; there is no minimum session length for this panel.
