This study examines the relevance of the simple random sampling technique in research on marital satisfaction in Nigeria. Simple random sampling is one of the most commonly applied sampling approaches in quantitative survey-based research. It is particularly suitable for populations that are relatively homogeneous and evenly distributed. Under this technique, every member of the population has an identical chance of being selected, as participation is determined purely by chance rather than researcher discretion. While simple random sampling offers notable strengths—such as minimizing selection bias, enhancing representativeness, and ensuring equal selection probability—it also presents certain limitations. These include the practical difficulty of obtaining a complete and accurate sampling frame, the time-consuming nature of the process, and reduced effectiveness when the population is diverse or geographically scattered.
