average values and reduce and simplify the worksheet
I have a Excel2003 worksheet containing 2 columns and more than 20,000 rows.
Column €œB€ lists the names of objects and column €œA€ lists the values of repeated measurements for each object. The repeating times of measurement vary from object to object. I will need to average the measurement values for each object, and reduce the table to one object with one average value. Could somebody tell me how to do this? Thanks. Example: From: A B 1.8099 aa 1.8685 aa 1.8081 aa 2.0376 aa 1.4996 aa 1.984 aa 0.4723 bb 0.3107 bb 0.4174 bb 0.2281 cc 0.3621 cc 0.3618 cc 0.1087 cc 0.2929 cc 2.5983 dd 2.1616 dd To: 1.8346 aa 0.4001 bb 0.2707 cc 2.38 dd |
