针对国内应用型本科湖南文理学院院校概率统计课程的实训教学越来越多地注重Excel作为初学者操作平台的现状,就非平衡数据和嵌套结构的数据在Excel中实现方差分析的过程进行探究。突出以组内矫正数为主线整理数据后简化平方和分解公式的理念,使得Excel中进行方差分析时,数据整理流程完全格式化,平方和的分解步骤更为简洁,自由度分解、F检验等步骤不再繁琐,为非统计专业本科阶段借助Excel电子表格率先实现概率统计课程实训教学的宽口径模式提供借鉴。
針對國內應用型本科湖南文理學院院校概率統計課程的實訓教學越來越多地註重Excel作為初學者操作平檯的現狀,就非平衡數據和嵌套結構的數據在Excel中實現方差分析的過程進行探究。突齣以組內矯正數為主線整理數據後簡化平方和分解公式的理唸,使得Excel中進行方差分析時,數據整理流程完全格式化,平方和的分解步驟更為簡潔,自由度分解、F檢驗等步驟不再繁瑣,為非統計專業本科階段藉助Excel電子錶格率先實現概率統計課程實訓教學的寬口徑模式提供藉鑒。

With more practical teaching of domestic undergraduates’probability and statistics course focusing on the Excel, an operating platform for beginners, the variance analysis process of unbalanced data and nested structure data in the Excel was explored. The idea on correction number within the group after sorting data and simplified square sum decomposition formula was highlighted to make the data flow full formatting, the decomposition process more concise and the freedom decomposition and F test step less cumbersome in the variance analysis process of Excel, which provided a wide aperture mode that using Excel electronic form to realize practical teaching for non-statistics professional undergraduates’probability and statistics course.
