Report Statistics
Learn how TallyFlex calculates weighted averages for ABA behavior data, including frequency, duration, task analysis, and mastery metrics in your exported reports.
Report statistics in TallyFlex are the summary metrics calculated for each tracker when you export data - including weighted averages for frequency, duration, and percentage-based measures. Trusted by 10,000+ practitioners, TallyFlex is the ABA data collection app built for clinical accuracy - ensuring these calculations follow evidence-based standards so you can trust your reports.
What Each Statistic Means
| Tracker Type | ”Average” Shows | What It Tells You |
|---|---|---|
| Frequency | Occurrences per day | How often the behavior happens daily |
| Duration | Minutes per day | Total time spent on behavior each day |
| 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 |
Clinical Validity
TallyFlex’s calculations follow established ABA data analysis standards, including guidelines from Cooper, Heron & Heward’s Applied Behavior Analysis. This ensures your reports are suitable for:
- 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
