Top 5 Videos on Statistics & Applied Mathematics for Class 11 and 12 by PW

Statistics requires more than memorising definitions and formulas. You need to understand how data is collected and classified, distinguish related economic concepts, and apply the correct methods when solving numerical questions. If you confuse correlation with causation or struggle with hypothesis testing, revising multiple topics before your school examinations can become difficult.

Physics Wallah’s YouTube videos help you study Statistics through introductory explanations, topic-based revision and exam-focused question practice. You can build your foundation in Class 11 Economics, revisit important concepts before unit tests, or revise Inferential Statistics alongside Matrices and Determinants for Class 12 Applied Mathematics. These videos can help you strengthen concept clarity, practise numerical questions and prepare more confidently for your school examinations.

Video 1: Identify Important Statistics Topics Quickly for Unit Test 

Do you have limited time to revise Statistics before your unit test? This quick revision video covers important topics from Introduction to Statistics, Collection of Data, and Organisation of Data. You revisit the features, limitations, and functions of Statistics, primary and secondary data, census and sample methods, questionnaire surveys, enumerator methods, sampling types, and classification objectives. The topic-wise review helps you identify key definitions and theory points that need attention.
