Import items and a codebook
Read responses conservatively, apply declared missing codes, and validate the codebook for scale, direction, and response range.
PREMIUM R MARKDOWN WORKFLOW · VERSION 1.0.0
Turn raw questionnaire items into documented scale scores. Check item direction against your codebook, reverse-score, apply an explicit missing-item rule, and review reliability, so a quiet scoring error does not become a misleading result.

WHAT IS INSIDE
Run the synthetic example first, with its deliberately inserted problems, then adapt the codebook and settings to a de-identified working copy of your own data.
Read responses conservatively, apply declared missing codes, and validate the codebook for scale, direction, and response range.
Flag out-of-range and unreadable responses, review missingness by item, and keep a record of every change.
Compare inter-item correlations with the codebook and flag items that point the wrong way after reversal.
Apply the codebook's reversals, then compute mean or sum scores with a missing-item rule you set.
Report alpha and item statistics, check expected relationships, and export scored data, audit tables, and a scoring log.
DESIGNED FOR DISSERTATION DATA
Factor structure, measurement invariance, and validity evidence require a factor-analytic workflow, such as Psychometrics. Messy raw data may need Data Cleaning and Audit first.
