What is the difference in collecting information using a census or a sample method? Discuss with few examples. |
|
Answer» Census and sampling both serve the purpose of providing data and information about a population. Sample method: Under this technique, some representative units or informants are selected from the universe. These selected units are called samples. Based on the data collected from these samples, conclusions are drawn upon the whole universe. It is to be noted that if the size of the sample is considerably large and the samples have been properly selected, various results obtained from the study of the sample units, also hold good for the entire universe. Census method: Under this technique, each and every item or unit constituting the universe is selected for data collection. In the Indian Census, which is conducted once in ten years, this technique is invariably followed. |
