⭐ খুব গুরুত্বপূর্ণ Revision
Problem → Literature Review → Objectives/Questions → Hypothesis → Research Design → Sampling → Data Collection → Data Analysis → Interpretation → Report/Dissemination
Validity = measures what it should measure
Reliability = consistency
Independent variable = cause/intervention
Dependent variable = outcome
Population = whole group
Sample = selected part of population
Belmont = Respect for persons + Beneficence + Justice
