coefficient of correlation in excel 相关系数是用来衡量两个变量之间线性关系强度的一种统计量。在Excel中,可以使用CORREL函数来计算相关系数。 CORREL函数的语法如下: CORREL(array1,array2) 其中,array1和array2是需要计算相关系数的两个数组。 例如,我们有如下数据: 为了计算相关系数,我们选择空白单元格,输入=...
在校內模擬會考放榜活動中,同事以 EXCEL 計算出所謂 Coefficient of Correlation(相關係數),從而告訴學生,學校估計的會考成績比同學自己估計的準確,因為校方的相關係數較同學的接近 1。 慚愧地,身為數學授課員,也不能深入認識何謂相關係數(或許是很久以前曾經認識過,現在已歸還教授們),現在只能以我這個統計學行外人,...
