COVAR

COVAR 函數會傳回兩組數值的共變異數。

COVAR(樣本 1 數值, 樣本 2 數值)

樣本 1 數值： 包含第一組樣本值的集合。

樣本 2 數值： 包含第二組樣本值的集合。

附註

兩個集合必須具有相同的範圍。
如果字串值或布林值包含在集合內，則會將其忽略。
如果兩個集合完全相同，則共變異數與母群體的變數相同。

範例

假設您已為供熱用油的遞送費用以及溫度調節器的平均溫度設定（在此特定價格所涵蓋的期間）的更動進行定期記錄。

提供下列表格：

	A	B
1	價格	設定
2	4.50	64
3	4.20	65
4	3.91	65
5	3.22	66
6	3.09	66
7	3.15	66
8	2.98	68
9	2.56	70
10	2.60	70
11	2.20	72

=COVAR(A2:A11,B2:B11) 會傳回大約 -1.6202，表示二者之間存在相互關係（價格上漲時溫度調節器的溫度會降低）。共變異數是兩個變數彼此連動的程度測量值（在此情況下，為供熱用油的價格與溫度調節器的設定）。
