Question

Which of the following statements best describes the process that characterizes inferential statistics?

Descriptive methods are used to characterize the information in a population so that conclusions may be reached regarding samples taken from that population.
		Descriptive methods are used to obtain parameters that are then used to make inferences about the sample.
		Descriptive methods are used to obtain statistics that are then used to make inferences about the population.
		Finite populations are aggregated to obtain (nearly) infinite populations that can then be used to obtain parameters

Answer 1

we know that the inferential statistics is used to make inferences about the population data with the help of sample data. We can see that option A and B are incorrect as we never make inferences about sample using the population.

option C is correct because sample data is used for testing purpose and then we make inferences for population data using the sample data test result.

option D is incorrect because we never aggregate finite populations to obtain infinite population information. We just use sample data to make inference for population.
