The science of Statistics has assumed great importance in recent years. It was once known as the ???Science of Kings??? and its scope was extremely limited, but today the science of Statistics has become an all-important science, without which no other science can progress. Modern age is the age of Statistics and it is very correctly said that the extent of the economic development of a country can best be known by finding out the extent to which statistical organisation has developed there. Till recently the foreign government of our country and even our countrymen were very indifferent towards statistics. After independence of the country the era of economic planning started and along with it the importance of statistics increased considerably. In fact economic planning cannot be imagined in the absence of Statistical data.
