You are designing a field experiment to observe how people react to someone asking for directions on a college campus. Propose a specific, well-defined participant selection rule you could establish before data collection to prevent selection bias.
Question: You are designing a field experiment to observe how people react to someone asking for directions on a college campus. Propose a specific, well-defined participant selection rule you could establish before data collection to prevent selection bias.
Sample answer: A well-defined rule could be to approach every fourth person who walks past the campus library's main entrance alone between 10:00 AM and 12:00 PM.
Key points:
- The rule must be capable of being established before data collection.
- The rule must clearly and objectively dictate exactly who is included.
- The rule must eliminate the experimenter's ability to subjectively choose participants, thereby preventing bias.
Rubric: Full credit requires proposing a clear, objective rule that can be established prior to data collection and eliminates subjective choice by the experimenter in the moment.

What is the primary purpose of establishing explicit participant selection rules before data collection begins in a field experiment?
When conducting field experiments where participants are encountered naturally, researchers may adjust their selection criteria during data collection to ensure they capture the most interesting behaviors.
A researcher is studying helping behavior in a busy subway station. To prevent selection bias, arrange the following steps in the correct chronological order to show how participant selection rules are applied in this environment.
A researcher is conducting a field experiment on helping behavior in a public park. To ensure the results are valid and free from experimenter bias, they must implement strict participant selection rules. Match each selection rule to the specific analytical safeguard it provides.
Match each component of participant selection rules in field experiments with its specific requirement or goal.
When conducting a field experiment where participants are encountered naturally, why is it essential to finalize selection rules before data collection begins?
A peer reviewer concludes that a field experiment lacks objectivity because the researcher chose which individuals to observe based on their 'approachability' in the moment. To reach the standard of a high-quality empirical study, the researcher should have utilized _____ selection rules established before data collection to eliminate this source of bias.
A researcher conducting a field experiment on helping behavior in a public park writes a rule beforehand stating that they will study only every third person who walks past a specific park bench. If the researcher adheres strictly to this predetermined rule during data collection, they are correctly applying participant selection rules to prevent experimenter selection bias.
A research team plans to observe pedestrian reactions to a staged emergency in a subway station. If they do not establish explicit inclusion criteria before beginning, the study's internal validity is threatened by _____ bias, which can occur intentionally or unintentionally during data collection.
To ensure a field experiment minimizes selection bias and maintains methodological rigor, arrange the following steps of the participant selection workflow in the correct chronological order:
Describe the requirements for establishing participant selection rules in a field experiment where participants are encountered naturally, and explain the primary purpose of having these rules.
Diagnose the methodological flaw in this researcher's approach based on the principles of participant selection in field experiments. What is the specific consequence of this flaw?
