Created November 11, 2026 by Forensic Psychology.
All 12 rows are invented. No real participants, study, patient records or empirical findings.

participant_id: unique invented identifier S01 through S12.
condition: invented group label A or B; six rows per group.
comprehension_score_out_of_10: invented integer from 0 to 10.
No missing values are included. Do not invent a missing-value rule for real data.

TASK
1. Check unique IDs, permitted conditions and score range.
2. Calculate n, sum and mean for each group.
3. Calculate B mean minus A mean.
4. Write one descriptive sentence and two things the data cannot establish.
5. Change one score in a separate copy and document its impact.

EXPECTED ORIGINAL OUTPUT
A: n=6, sum=36, mean=6.00
B: n=6, sum=45, mean=7.50
B minus A mean=1.50 points
No test of statistical significance is provided. This exercise cannot establish
causality, real-world effectiveness, generalizability or an individual's ability.
