About

Research Corner is the English edition of Góc Nghiên Cứu, a free research-methods site. We write for students working on a thesis, master's students, lecturers, and anyone who needs a survey that produces usable data.

Here you will find:

• Statistics tools that run in your browser: sample size, Cronbach's alpha, EFA, regression, PLS-SEM, CFA and CB-SEM, mediation and moderation, and a results-chapter report builder. Your data never leaves your computer.
• Validated scales with the original English items and APA sources, and scales grouped by concept.
• Practical guides for each step: questionnaire design, sampling, data cleaning, reliability and reporting.

Scale items are copied verbatim from open sources with a link to check against, references are checked through Crossref, and the statistics tools are compared with R reference values on every update. See how the tools are verified against R.

Research Corner is a referral partner of Genius Data (referral link), a paid-response survey platform: if you sign up through a link on the site we may earn a commission at no cost to you. Genius Data only appears where it is relevant, when you need more respondents from the right population, always next to the free options and always labelled as a referral link.
