Suppose you are designing a replication of the university student writing study using a sample of 100 students. How would you apply random assignment to place these students into the traumatic and neutral writing conditions to ensure a valid between-subjects design?
Question: Suppose you are designing a replication of the university student writing study using a sample of 100 students. How would you apply random assignment to place these students into the traumatic and neutral writing conditions to ensure a valid between-subjects design?
Sample answer: To apply random assignment, I would assign each of the 100 students a unique number from 1 to 100 and use a random number generator to assign 50 students to the traumatic writing condition and the remaining 50 to the neutral writing condition. This ensures that every student has an equal chance of being placed in either group and that each student participates in only one of the two writing tasks.
Key points:
- Propose a random assignment method (e.g., random number generator, coin flip).
- Distribute students into either the traumatic writing or neutral writing condition.
- Ensure each student is assigned to only one condition, fulfilling the between-subjects design.
Rubric: The answer should describe a random assignment procedure (e.g., random number generator, drawing names, coin toss) to place students into either the traumatic or neutral writing condition, ensuring each participant is assigned to exactly one task.

A researcher is developing a new between-subjects experiment to test if 'natural sunlight' in a workspace improves employee productivity compared to 'fluorescent lighting.' Which of the following procedural structures should the researcher build to ensure the study is a valid between-subjects design?
In the example of a between-subjects experiment involving university students, researchers compare a traumatic writing condition with a(n) _____ writing condition so that each participant completes only one type of task.
To evaluate the rigor of a between-subjects experiment comparing three therapies for agoraphobia, a researcher must verify that participants were _____ to their groups to ensure that any differences in outcomes are caused by the treatments rather than pre-existing participant traits.
A researcher studying the effect of background noise on reading comprehension randomly assigns 50 undergraduate students to read a passage in either a noisy environment or a quiet environment, with no student completing both conditions. This study matches the defining structure of a between-subjects experiment, as illustrated by the traumatic/neutral writing and agoraphobia treatment examples.
Analyze each specific design feature drawn from the between-subjects experiment examples (traumatic/neutral writing study and agoraphobia treatment study). Match each feature to the methodological threat it is specifically designed to prevent.
A peer reviewer is judging whether a proposed study—in which participants are assigned to separate groups receiving different writing tasks or different therapies—qualifies as a rigorous between-subjects experiment. Arrange the following evaluative criteria in the logically correct order, from the most foundational check to the final overall judgment of rigor.

Explain how the psychologist's setup illustrates a between-subjects design. What fundamental rule of between-subjects design is applied here, and why does this setup require comparisons to be made across different groups of individuals rather than within the same individuals?
