average and stdev from groups of data
Hi everybody,
I have data such below for a year, How do i calculate average and stdev from sample1 to sample4 on each date?. Is there any functions or formulas to automatically calculated it ? Ex: what is average and stdev from date 3/1/06 ? I have tried to calculate by subtotals function, but it only can calculate by colums. Date sample1 sample2 sample3 sample 4 1/1/06 2 3 1 2 1/1/06 2 1 3 2 1/1/06 3 0 2 3 2/1/06 1 2 1 0 3/1/06 2 1 3 2 3/1/06 0 2 1 3 Thanks, Charlie |

Assuming that A1:E1 contains your headers/labels, and A2:E7 contains
your data, let G2:G4 contain 1/1/06, 2/1/06, and 3/1/2006... H2, copied down: =AVERAGE(IF($A$2:$A$7=G2,$B$2:$E$7)) ....confirmed with CONTROL+SHIFT+ENTER, not just ENTER. For STDEV, change AVERAGE to STDEV. Hope this helps!
