In this study, we investigated whether computer-animated graphics are more effective than static graphics in teaching statistics. Four statistical concepts were presented and explained to students in class. The presentations included graphics either in static or in animated form. The concepts explained were the multiplication of two matrices, the covariance of two random variables, the method of least squares in linear regression, alpha error, beta error, and strength of effect. A comprehension test was immediately administered following the presentation. Test results showed a significant advantage for the animated graphics on retention and understanding of the concepts presented.
在本研究中，我们调查了在统计学教学中，计算机动画图形是否比静态图形更有效。向学生们在课堂上呈现并解释了四个统计概念。这些呈现包括静态或动画形式的图形。所解释的概念有两个矩阵的乘法、两个随机变量的协方差、线性回归中的最小二乘法、α错误、β错误以及效应强度。在呈现之后立即进行了一次理解测试。测试结果表明，动画图形在对所呈现概念的记忆和理解方面具有显著优势。
