What type of research is it (quantitative, qualitative, and design)? What was the research question(s) or hypothesis? What is the sample, the sample size, and sample attributes?

This research is quantitative in nature, and its aim is to investigate the effect of peer feedback on student performance. The research question for this study was “Does providing students with feedback from their peers have an effect on their academic performance?”

The sample for this study was composed of 180 undergraduate students enrolled in a psychology course at a university in the United States. These students were divided into two equal groups: one that received feedback from peers, and one that did not receive any peer feedback. Sample attributes included gender (male/female), age (18-25 years old), ethnicity (White, Black/African American, Hispanic/Latino, Asian or Pacific Islander) and major (psychology or non-psychology). All participants were asked to complete pre- and post-test surveys regarding their academic performance before and after receiving peer feedback.

Through this research design, the researchers hoped to gain a better understanding of how student performance changes when they are given constructive criticism from those around them – which could ultimately lead to improvements in teaching strategies used by instructors in order to ensure optimal learning outcomes for all students.
