Questions and Answers

When can sample data be used to generalize about the entire population?

When the sample size is small

When the sample is selected in a representative manner (correct)

When the sample is selected without any specific criteria

What does it mean to infer from sample data?

To collect additional data to validate the sample findings

To assume that the sample represents only a small portion of the population

To disregard the sample and focus only on individual cases

Study Notes

Sampling and Generalization

Sample data can be used to generalize about the entire population when the sample is representative and randomly selected.
The purpose of sampling techniques is to obtain a manageable subset of data that can be used to make inferences about the entire population.

Inference and Census

To infer from sample data means to draw conclusions about the entire population based on the trends and patterns observed in the sample.
One should not assume that a census would necessarily provide more useful results than collecting data from a sample, as a census may be impractical, time-consuming, and expensive, and may not provide more accurate results.

Collecting Data from the Entire Population

It is possible to collect data from an entire population in situations where the population is small, easily accessible, and has a clear boundary, such as a school or a small business.
