The following sentence uses parallel construction when reporting results: 'The treatment group had a mean of 23.40 (SD = 9.33), while 20.87 was the mean of the control group, which had a standard deviation of 8.45.'

Which of the following sentences best demonstrates the use of parallel construction when reporting the results of a study comparing two experimental conditions?

To report results clearly, researchers use parallel construction by keeping the phrasing consistent across comparisons. Match each opening result statement with the concluding phrase that best maintains parallel construction.

In psychological reporting, parallel construction requires that comparisons between groups follow the exact same grammatical pattern to ensure clarity. Analyze the structure of the following first clause: 'The treatment group had a mean of $23.40$ ($SD = 9.33$).' Now, arrange the following segments to complete the sentence so that the control group's results mirror that structure perfectly.

When reporting research results using parallel construction (e.g., 'The treatment group had a mean of $23.40$ ($SD = 9.33$), while the control group had a mean of $20.87$ ($SD = 8.45$)'), what is the primary benefit of this consistent phrasing?

A peer reviewer assesses the following sentence in a psychological results section: 'Participants in the exercise condition had a mean heart rate of $120$ bpm ($SD = 10$), while $72$ bpm ($SD = 5$) was the mean heart rate for the sedentary group.' The reviewer evaluates this phrasing as inefficient for scientific communication because it fails to maintain _____, which would have allowed the reader to compare the two groups using an identical grammatical template.

Effective reporting of psychological results relies on parallel construction to improve clarity. Match each phrasing example or feature with the reason it either helps or hinders a reader's ability to interpret data.

A student writes the following sentence in their results section: 'Participants in the morning condition had a mean accuracy of $82.4\%$ ($SD = 7.1$), while in the afternoon condition, the mean accuracy was $78.9\%$, with a standard deviation of $6.5$.' This sentence is an example of parallel construction in reporting results.

When analyzing the structure of the non-parallel sentence—'The treatment group had a mean of $23.40$ ($SD = 9.33$), while $20.87$ was the mean of the control group, which had a standard deviation of $8.45$'—a central structural problem is that the second clause begins with _____ rather than with the group label, inverting the subject–statistic order established in the first clause.

A peer reviewer determines that the sentence 'The treatment group had a mean of $23.40$ ($SD = 9.33$), while $20.87$ was the mean of the control group, which had a standard deviation of $8.45$' violates parallel construction and must be revised. Arrange the following evaluation and revision steps in the most defensible logical order.

Define parallel construction in the context of reporting scientific results. Using the examples from the course text involving the treatment group (mean of $23.40$, $SD = 9.33$) and control group (mean of $20.87$, $SD = 8.45$), explain the formatting difference between parallel and nonparallel construction and describe the primary benefit parallel construction provides to readers.

Diagnose the formatting error in the student's draft based on the concepts of parallel construction. Explain why this error makes it difficult for readers to comprehend the results, and explain how the student should restructure the sentence to resolve the issue.

Apply the principles of parallel construction to rewrite the following nonparallel sentence, ensuring that the grammatical structure for both groups is identical and all statistics are preserved: 'The experimental group had a mean score of $85.50$ ($SD = 6.20$), whereas $72.10$ was the mean of the comparison group, which had a standard deviation of $5.80$.'
