Why This Course Matters?
One of the top reasons research papers get rejected is poor methodology — and at the heart of methodology lies sample size calculation.
- Too few participants → underpowered, unreliable results
Too many participants → wasted resources and ethical issues
C3 equips you with practical tools and real-world training to calculate sample sizes across different study designs, from prevalence studies to survival analyses.
This is the difference between “just another study” and a publication-ready research project.
Available in Both Languages:
✔ Arabic version → All concepts explained in Arabic, while keeping all scientific terms, tests, and software in English, so you can publish confidently.
✔ English version → Full instruction in English by Dr. Negida, ideal for international researchers.
👉 You get both versions included in your enrollment — at no extra cost.
