Report Statistics
Learn how TallyFlex calculates report statistics for frequency, duration, latency, percent correct, interval recording, and task analysis data.
Report statistics in TallyFlex are the summary metrics calculated for each tracker when you export data. Count and time-based measures summarize the data collected for that tracker, while percentage-based measures summarize the underlying trials, intervals, or steps.
What Each Statistic Means
| Tracker Type | ”Average” Shows | What It Tells You |
|---|---|---|
| Frequency | Occurrences per data day | How often the behavior happens |
| Duration | Minutes per data day | Total time spent on behavior |
| Latency | Seconds per response | How quickly the learner responds |
| Percent Correct | Overall accuracy | True performance across all trials |
| Interval Recording | Percentage of intervals | True occurrence rate across all intervals |
| Task Analysis | Percent independent | True independence across all steps |
Why Weighted Averages Matter
For percentage-based data (Percent Correct, Intervals, Task Analysis), TallyFlex uses weighted averages instead of simple averages. This ensures each trial, interval, or step counts equally - regardless of which day it occurred.
Example: Why This Matters
Imagine a learner’s Percent Correct data:
| Day | Result | Trials |
|---|---|---|
| Day 1 | 1/1 = 100% | 1 trial |
| Day 2 | 1/10 = 10% | 10 trials |
| Day 3 | 8/10 = 80% | 10 trials |
Simple average of percentages: (100 + 10 + 80) / 3 = 63%
This is misleading - Day 1 had only one trial but gets equal weight to days with ten trials.
Weighted average (what TallyFlex uses): (1 + 1 + 8) / (1 + 10 + 10) = 10/21 = 48%
Each of the 21 trials contributes equally. This accurately represents true performance.
Quick Reference
| Tracker Type | Calculation |
|---|---|
| Frequency | Total occurrences / days with data |
| Duration | Average of daily totals (in minutes) |
| Latency | Total latency / total responses |
| Percent Correct | Total correct / total trials |
| Partial Interval | Behavior intervals / total intervals |
| Whole Interval | Behavior intervals / total intervals |
| Task Analysis | Independent steps / total steps |
For count and time-based measures, 0 is included when the tracker was observed and the result was zero. Blank values mean there was no data for that tracker in that period, so they are not included in the average.
Using Report Statistics in Review
These summaries can support qualified clinical review, documentation, and team discussion when interpreted with the full record and professional judgment:
- Insurance documentation
- Progress reports for parents
- Clinical team meetings
- Treatment planning decisions
Tips
- Compare apples to apples - When reviewing progress, consider the number of trials or intervals, not just percentages
- Check the totals - Reports include raw counts (correct/total, independent/total) alongside percentages
- Export for deeper analysis - Excel exports include daily breakdowns for custom analysis
