How does SAS works in specific case

[faith]

Hi,

I have data for five different lots:

Lot # Day 1, Day 2, Day 3, Day 4, Day 5

A : 10.1, 10.2, 10.0, 9.9, 10.0
B: 10.0, 10.0, 9.9, 9.9, 9.8
C: 9.9, 9.9, 10.0, 10.1, 10.1
D: 9.9, 10.0, 10.0, 10.1, 10.2
E: 10.1, 10.1, 10.0, 10.0, 9.9

Results vary when I do the SAS cumulatively (A,B,C,D&E) and individually for each lot. Would anybody tell me on how SAS works?

Faith,

You need to be more specific. Show your procedures and log.
