Explanation:

Classify surveys

Asking people questions about their habits is a Sample Survey because it gathers data by asking a subset of a population to self-report information.

  • Statement 1: Asking people at a park about their weekend habits is a sample survey. This is True.
  • Statement 2: Testing cough medicine effectiveness is an active intervention, not a survey. This is False.

Classify experiments

An experiment actively imposes a treatment on subjects to observe the response and establish cause-and-effect.

  • Statement 3: Testing paper towel absorption brands involves controlled testing/treatments. This is True.
  • Statement 5: Counting coyotes in a field is passive observation without imposing treatments. This is False.

Classify observational studies

An observational study measures characteristics of a sample without attempting to manipulate or influence the subjects.

  • Statement 4: Conducting a taste test involves giving subjects specific sodas to drink (imposing a treatment/intervention), making it an experiment rather than a passive observational study. This is False.
  • Statement 6: Observing and recording bird migration patterns is passive observation with no intervention. This is True.
