☀️Introduction to Quantitative Reasoning Course  for B.Ed/BS/BCS/MS/M.Phil Level Students Quantitative Reasoning (QR) also known as quantitative literacy or numeracy, is an ability and an academic skill to use mathematical concepts and procedures.  The literal meaning of the word " Quantitative " is " the discrete or continuous data that is often counted or measured in numerical values ." Whereas, the literal meaning of the word " Reasoning " is " the rational and logical thinking ." QR is a " Habit of Mind " which 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. Undergraduate level learners often require to have some basic knowledge about statistics numeracy, quant...
