Defining Complete Population Enumeration
The question asks for the specific term used when every single item in a defined group, or population, is counted or listed. This process is referred to as a complete enumeration.
Identifying the Correct Term: Census
A Census is defined as the process of systematically acquiring and recording information about every member of a given population. It involves a complete enumeration of all units in the population.
Distinguishing from Sampling Methods
Let's examine why the other options are not suitable:
- Unrestricted sampling: This is a type of probability sampling where each unit has an equal chance of selection, but it typically involves studying only a *part* of the population, not all members.
- Non-probability sampling: This method selects samples based on criteria other than random chance (e.g., convenience). It does not involve enumerating the entire population.
- Sample survey: This method involves collecting data from a representative *sample* (a subset) of the population, not the entire population itself.
Therefore, the only option that accurately represents a complete enumeration of all items in the population is a Census.
Important Questions from Sampling
The process of converting the analog sample into discrete form is called ______.
Respondents of a recent sample survey provided names of friends they thought would be likely users of a new product. These friends were contacted, completed a survey, and asked to supply names of other likely users. Which method of sampling has been used in this survey ?
Which one among the following relates to the probability-based sampling technique?
In which process is the flat-top pulse amplitude modulated signal generated?
Consider a population of 3 units having values 2, 4 and 6. A simple random sample (without replacement) of 2 units is to be drawn from the population. Let M denote the sample mean of this sample. Then which of the following statements are true?
