Know what you are buying.
PDF purchases and live training have different delivery terms. The selected format, payment route, and applicable conditions are confirmed before payment.
How is the PDF delivered?
After payment is verified, a personal download link is sent to the email address and WhatsApp number supplied with the purchase request. Keep those details accurate and retain the receipt.
May I print or share the course?
You may save and print a copy for your own learning. Redistribution, resale, public upload, classroom distribution, or inclusion in another commercial product is not permitted under the personal licence.
Can I modify an existing questionnaire?
Possibly, subject to permission and the effect of changes on meaning and measurement evidence. The course explains how to document adaptation.
Does a high Cronbach's alpha prove validity?
No. Alpha addresses a form of internal consistency under assumptions; it does not establish content, structure or intended score interpretation.
