What term refers to the complete count of all relevant members within a population?

• A. Census
• B. Sample
• C. Population
• D. Parameter

Answer: (A)

The main idea here is counting every member in a defined group. That complete counting is known as a census. When you perform a census, you’re collecting data on every individual in the population, which provides exact information for the whole group. A sample, by contrast, looks at only a portion of the population, not everyone. The population is the entire group you’re interested in studying, not the act of counting. A parameter is a numerical trait that describes the population (like the average age or proportion), not the act of counting people. So the term for the complete count is census.
