对比ChatGPT3.5与4在统计作业中的准确率，揭示免费版可能带来学习不平等
Equity in the Use of ChatGPT for the Classroom: A Comparison of the Accuracy and Precision of ChatGPT 3.5 vs. ChatGPT4 with Respect to Statistics and Data Science Exams
- 比较免费版（3.5）与付费版（4）在统计题解答中的表现差异
- 发现4版本在数据科学题目上准确率显著更高
- 提醒教育公平问题：技术门槛可能影响低收入学生学习机会
大学教育历来被视为提升收入和社会地位的途径。许多高校为吸引优秀但经济困难的学生而提供奖学金，涵盖学费、教材、住宿和餐饮。然而，部分开支如使用生成式AI平台并未包含在资助范围内。当前最流行的平台是ChatGPT，其存在免费版（ChatGPT3.5）与付费版（ChatGPT4）。本文研究二者在典型入门级统计课程作业与数据分析任务中的表现差异，评估无法负担更高级别工具的学生是否在完成项目与掌握方法上处于劣势。结果表明，使用更先进模型的学生在答题准确性与精确度方面具有显著优势，凸显技术资源不平等对教育公平的影响。
原文摘要 · Abstract (English)
A college education historically has been seen as method of moving upward with regards to income brackets and social status. Indeed, many colleges recognize this connection and seek to enroll talented low income students. While these students might have their education, books, room, and board paid; there are other items that they might be expected to use that are not part of most college scholarship packages. One of those items that has recently surfaced is access to generative AI platforms. The most popular of these platforms is ChatGPT, and it has a paid version (ChatGPT4) and a free version (ChatGPT3.5). We seek to explore differences in the free and paid versions in the context of homework questions and data analyses as might be seen in a typical introductory statistics course. We determine the extent to which students who cannot afford newer and faster versions of generative AI programs would be disadvantaged in terms of writing such projects and learning these methods.
