Anonymization and analysis method

How the dashboard protects students while preserving instructional insight

The original questionnaire contained direct identifiers. This app does not include the raw CSV and does not expose names, registration numbers, contact details, batch labels or raw open-ended responses.

1. Data minimization

Only the variables required for workshop design were retained: prior experience flags, Likert confidence ratings, knowledge-check scores, anonymous indices, and aggregate open-response themes.

2. Removed identifiers

Name, registration number, email/contact, exact timestamp and year/batch labels were removed. Open-ended responses were coded into themes and not displayed verbatim.

3. Pseudonymous records

The scatterplot uses anonymous IDs such as P001. These are not linkable to the original respondent identities in the app package.

4. Aggregation threshold

The dashboard emphasizes group patterns, percentages, and means. It avoids individual text examples and small-group identity labels.

5. Thematic coding

Open-ended answers were coded into non-identifying themes such as recruitment, privacy, gamification, IoT, responsible AI and practical HRM tools. A response could belong to more than one theme.

6. Interpretation limits

The survey covers one cohort of 95 students. Findings should be used for instructional design, not as a generalizable national estimate of Sri Lankan HRM students.
