Question

select the correct answer.

a zoologist researched the feeding habits of lemurs. she collected data by studying the lemurs in a zoo exhibit for a one-month period and drew conclusions based on her data.

what kind of statistical study did the zoologist conduct?

observational study
survey
theoretical study
experiment

Explanation:

Analyze the researcher's methodology

The zoologist collected data by studying (watching/monitoring) the lemurs in their naturalistic environment (a zoo exhibit) without manipulating any variables, assigning treatments, or influencing their behavior.

Classify the type of study

• Observational study: The researcher observes and records behavior/outcomes without intervening or imposing treatments. This matches the zoologist's actions.
• Survey: Involves asking subjects questions to gather data, which is not applicable to lemurs.
• Experiment: Requires imposing a treatment on subjects to observe its effects, which did not occur here.
• Theoretical study: Based on mathematical models or theoretical principles rather than empirical observation.

Answer:

• observational study (Correct answer)
• survey
• theoretical study
• experiment
