값있는 데이터에 대해서만 평균, 표준편차, 분산을 구하고 싶어요

아래와 같은 표가 있습니다. 4월부터 12월까지 영희와 철수의 시험성적인데요. Data가 Null값이 아닌 데이터에 대해서만 평균, 표준편차, 분산값을 구하고 싶습니다. 평균값의 경우 averageif 를 사용하면 되는데 표준편차, 분산은 어떤함수를 사용해야하는지 모르겠네요.   <TABLE style="WIDTH: 487pt; BORDER-COLLAPSE: collapse" border=0 cellSpacing=0 cellPadding=0 width=649> <COLGROUP> <COL style="WIDTH: 48pt" width=64> <COL style="WIDTH: 103pt;

첫댓글 안녕하세요?
표준편차는 STDEV 분산은 VAR함수를 이용하시면 됩니다.

STDEV와 VAR을 이용하여 범위를 지정할 경우 빈칸의 0 도 계산되어 집니다.
즉 제가 원하는 것은 영희에 대하여 STDEV(89,95)이지 STDEV(0,89,0,95)가 아닙니다.

^^; 그러셨군요. 배열수식입니다.=STDEV(IF(B2:E2<>0,B2:E2,""))
수식입력후 CTRL+SHIFT+ENTER로 마무리 해보셔요.

네, 바라던 값이 나오네요. 그런데 배열수식이 뭔가요? 전 초보라서...
