Participant Selection Rules

Which of the following is the defining characteristic of a field experiment?

In a field experiment, the researcher sacrifices the ability to actively manipulate the independent variable in exchange for conducting the study in a natural, real-world setting.

A researcher investigates whether different types of background noise in a university library affect student concentration. Match each element of this study to the characteristic of a field experiment it represents.

A researcher is interested in how 'environmental prompts' influence littering in public parks. Rank the following research scenarios from the least to the most representative of a high-quality field experiment.

Match each core component of a field experiment's definition to the description that correctly identifies its role in a research study.

Which statement best describes the primary trade-off a researcher makes when choosing to conduct a field experiment rather than a laboratory experiment?

A field experiment is described as a methodological hybrid because it utilizes a natural setting to maintain high external validity while relying on the active manipulation of an independent variable to establish _____ validity.

A researcher wants to study social compliance. She instructs a confederate to drop papers in a busy university hallway either while wearing a formal suit or wearing casual clothes, and measures how many passersby help pick up the papers. Because she is manipulating an independent variable (clothing type) in a natural setting (hallway) and attempting to control for the time of day, this study is classified as a field experiment.

In a field experiment, the researcher actively manipulates an independent variable in a natural setting. However, the study's ability to yield high internal validity is directly dependent on the level of _____ achieved by the researcher over extraneous variables.

Rank the following research scenarios from the least aligned (1) to the most aligned (3) with the definition of a high-quality field experiment that yields high internal and external validity.
