^ma21 60^pl 88 4 4 ^juThis program was inspired by the need to analyse, on a regular basis, the concrete cube results on a construction project in the Middle East. It is frequently useful to be able to obtain the mean and standard deviation of say, the most recent 120 7-Day Cubes, the most recent 120 28-Day Cubes and the most recent 240 cube density results. I can assure users that using this program is much easier than starting from scratch each time.!!! ^skM.Cracknell, 6 Stratton Mews, Off South Street, Leighton Buzzard, Bedfordshire LU7 8NT, England.
