Social research examines social phenomena using concepts from the social sciences. It aims to illuminate changes in society, but human behavior is irregular and difficult to predict compared to natural sciences. There are different types of social research including descriptive research that reports current conditions, analytical research that critically evaluates existing data, applied research that solves problems, and fundamental research that develops theories. Research can also be qualitative and focus on meanings, or quantitative and rely on measurable data. The scientific method is a systematic process used in social research involving observation, hypothesis, and verification through empirical evidence, concepts, and logical reasoning. However, whether human behavior can truly be studied scientifically is debated.
