What is Statistics: Variables, Measurement Scales, Populations, Samples, Parameters Sampling

Statistics forms the backbone of educational research, social science inquiry, and data-driven decision-making. This lecture provides a clear, systematic, and exam-oriented introduction to the fundamentals of statistics, focusing on core concepts essential for students, researchers, and educators. The video begins with an explanation of variables, distinguishing between continuous and discrete variables, with examples relevant to educational and social science research. It then introduces measurement scales—nominal, ordinal, interval, and ratio—highlighting their defining characteristics, levels of measurement, and implications for statistical analysis and choice of tests. A detailed discussion follows on population and sample, clarifying the conceptual and practical differences between the two. The lecture explains parameters and statistics, emphasizing how parameters describe population characteristics while statistics are derived from sample data and used for estimation and inference. The video further examines sampling, outlining basic sampling concepts and common issues encountered in data collection. Special attention is given to sample bias, including its sources, consequences, and impact on the validity and generalizability of research findings. Throughout the lecture, concepts are explained with methodological clarity to support accurate data interpretation and research rigor. This video is particularly useful for B.Ed., M.Ed., Ph.D. coursework, UGC NET/SET (Education), research methodology papers, and competitive examinations, as well as for beginners seeking a strong foundation in statistics for educational and social science research. #Statistics #FundamentalsOfStatistics #StatisticsBasics #VariablesInStatistics #ContinuousVariables #DiscreteVariables #MeasurementScales #NominalScale #OrdinalScale #IntervalScale #RatioScale #PopulationAndSample #ParametersAndStatistics #Sampling #SampleBias #EducationalResearch #ResearchMethodology #StatisticsForEducation #HigherEducation #UGCNETEducation #BEd #MEd #PhDCoursework
