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
  • When the sample includes only specific cases

What is the purpose of sampling techniques?

  • To reduce the amount of data needed by considering data from a sub-group (correct)
  • To generalize about all cases without collecting any sample data
  • To ensure collection of data from all possible cases or elements
  • To make inferences without considering any sub-group data

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
  • To draw conclusions about the entire population based on the sample (correct)

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.
