Author Contributions

This page records the agreed author roles for the textbook Quantitative Analysis with Small Samples: A Practical Guide for Students and Early-Career Researchers.

Mohammed Ali Sharafuddin

Mohammed Ali Sharafuddin (ORCID: 0000-0001-5247-2964) led the textbook concept, overall structure, chapter planning, pedagogical design, Quarto production workflow, reproducibility strategy, R-based examples, applied statistical framing, cover development, and publisher-readiness preparation. He coordinated the open textbook direction, licensing decisions, repository organisation, and final submission planning.

Ahsan Ahmed Jaleel

Ahsan Ahmed Jaleel (ORCID: 0009-0004-5576-8700) contributed mathematical and statistical expertise, particularly in strengthening the accuracy of quantitative explanations, modelling logic, assumptions, and interpretation. His background in mathematics and his current work on gamified and simulation-based learning support the textbook’s emphasis on clear learning design, student engagement, and rigorous yet accessible explanation.

Meena Madhavan

Meena Madhavan (ORCID: 0000-0003-1244-5392) contributed management, logistics, maritime, supply chain, and applied business research expertise. Her experience in business sustainability, maritime logistics, digital transformation, Industry 5.0, green supply chain management, blue economy research, and management education supports the applied examples, case orientation, and early-career researcher positioning of the book.

Shared responsibility

All authors are responsible for reviewing the final manuscript before public release, checking their biographical details and affiliations, confirming the licence statement, and approving the final version submitted to the publisher or deposited with DOI and ISBN metadata.
