Census method research is__________ percentage enumeration of sample?

Correct option is D

​100%​

The census method of research refers to the collection of data from every single individual in the population, rather than selecting a sample. This method involves enumerating the entire population and is typically used when accurate and comprehensive data is required from the whole group.

In the census method, 100% of the population is surveyed, making it different from sample surveys where only a subset (sample) of the population is studied. The goal is to gather data that represents the complete population.

Information Booster:

1. Census Method: The census method is characterized by total enumeration, meaning all members of a population are surveyed. It is typically used for national population censuses or other large-scale surveys.
2. Advantages: The primary advantage of the census method is the completeness of data, as it includes every individual in the population. This eliminates sampling errors and provides accurate population figures.
3. Disadvantages: However, the census method can be time-consuming, expensive, and difficult to organize, especially for large populations. It requires a significant amount of resources and manpower.
4. Uses: The census method is widely used by governments for population censuses, census of agriculture, and economic surveys to gather data about the entire population.
5. Sample Surveys: In contrast to the census method, sample surveys are less costly and time-consuming, as they collect data from a small subset of the population (a sample) and use statistical methods to make inferences about the larger group.

Additional Information:

1. Option 1 - 25%: This percentage is far too low for a census, which by definition includes the entire population. A sample survey could be conducted with 25% of the population, but not a census.

2. Option 2 - 50%: Similarly, 50% would be typical of a sample survey, not a census. In the census method, the aim is to capture 100% of the population, not a fraction of it.

3. Option 3 - 75%: A 75% survey would be a large sample, but still not a full census. A full census aims to include everyone, i.e., 100% of the population.
