Case Study Questions Collection of data Class 11 Economics  

Statistics does not recognise individual items. Consider the statement, “the weight of Mr X in the college is 70 KG”. This statement does not constitute statistical data. Statistical methods are not going to investigate anything about this statement. Whereas, if the weights of all the students of the college are given, statistical methods may be applied to analyse that data. Statistics is both a science and an art. It is systematic and finds applications in studying problems in economics, business, astronomy, physics, medicine etc. Statistical methods are sophisticated in nature. Everyone is not expected to possess the intelligence required to understand and to apply these methods to practical problems. This is the job of an expert, who is well-versed with statistical methods.
