Introduction to Quantitative Reasoning Course   Quantitative Reasoning (QR) is an ability and an academic skill to use mathematical concepts and procedures. QR often involves interpretation of empirical and numerical data, identification of patterns, flow charts, geometrical shapes, and diagrams for identifying real life problems including offering viable solutions.  QR requires logical reasoning and critical thinking to analyse the real life issues and making informed decisions. Learners often require to have some basic knowledge about statistics numeracy, quantitative values, ratio as well as descriptive and inferential statistical analyses. Hence, in order to have reasonable grasp on QR, learners require to have the basic knowledge about Statistics. In simple words, Statistics plays a very pivotal role in understanding Quantitative Reasoning. What is Statistics? Statistics is one of the Branches of Applied Mathematics or  science of collecting, organising, analysing,...
