    "content": "**No duplicates were found, either exact or near-duplicate on the attribute level.**\n\nThe check I ran over `raw.Social_media_impact_on_life` returned:\n\n- **Total rows:** 4,500\n- **Distinct `Student_ID` values:** 4,500, so every row has a unique key and the key is never repeated.\n- **Distinct attribute combinations:** 4,500. I grouped on the full set of student attributes (excluding the ingestion metadata columns) and no combination appeared more than once.\n- **Repeated combinations:** 0. No rows fall into a repeated group, and the maximum repeat count is 1.\n\n**Interpretation:** the table holds one row per student, and no two students share an identical profile. That rules out exact duplicates and also duplicates that differ only by `Student_ID`. This is the strict form of near-duplicate: rows identical on every attribute except the ID.\n\n**Limitation:** I did not test fuzzy near-duplicates, such as rows that match on most columns but differ slightly on a numeric value like GPA or sleep hours. The check shows no re-keyed copies of the same record. It does not rule out two students with very similar but not identical profiles. Such similarity would be expected in survey-like data and would not necessarily be a data-quality problem."
