Background:

Student anxiety about statistics may lead to poorer learning outcomes.

Objective:

The purpose of this study was to evaluate an exercise designed to teach students in an introductory statistics class the principles of bivariate regression and to emphasize how statistical tools used by psychologists are also implemented in other fields.

Method:

Students used a published model on the relationship between tooth size and the length of great white sharks to estimate the length of extinct sharks and to explore factors that could affect the accuracy or validity of regression analyses. Data from an anonymous self-report scale were used to assess the activity.

Results:

More than 95% of respondents agreed or strongly agreed that the activity was engaging, approximately 95% of students agreed or strongly agreed that the activity helped them learn about factors that can lead to problems with bivariate correlation/regression, and approximately 91% of respondents correctly answered a question designed to assess basic content acquisition.

Conclusion:

Feedback data suggest that the exercise was successful in achieving its content and process learning goals.

Teaching Implications:

Implementation of similar exercises may improve student engagement and outcomes in psychology statistics courses.

“跳跃鲨鱼”：跨学科活动，以双变量回归原理吸引学生

背景：

学生对统计数据的焦虑可能会导致学习效果较差。

客观的：

这项研究的目的是评估一项旨在设计入门级统计学班学生的二元回归原理，并强调心理学家使用的统计工具在其他领域也将如何实施。

方法：

学生使用已发表的模型来研究牙齿大小与大白鲨的长度之间的关系，以估计灭绝鲨鱼的长度，并探索可能影响回归分析准确性或有效性的因素。来自匿名自我报告量表的数据用于评估活动。

结果：

超过95％的受访者同意或强烈同意这项活动的参与，大约95％的学生同意或强烈同意这项活动帮助他们了解了可能导致双变量相关/回归问题的因素，约91％的受访者正确回答了旨在评估基本内容获取的问题。

结论：

反馈数据表明，该练习成功地实现了其内容和过程学习目标。

教学意义：

进行类似练习可以提高学生在心理学统计学课程中的参与度和学习成果。
