Our observations in field test tend to sample averages, since it is difficult to sample in great detail. As a result, we tend to observe only averages and, unless very scrupulous in our thinking, assume those (macro) averages reflect the experience of critters operating on a micro scale. The average temperature here in my part of Alberta is probably around plus five Celsius. That is hardly what one would consider a good temperature for growing wheat or water sports -- or skiing, for that matter. Nonetheless, Alberta is known for all the above. Today, however, the temperature is near minus twenty-seven, roads are closed and we are expecting wind chills of minus forty (C or F -- take your choice). My point is that averages don't tell us everthing we need to know, whether the average is over time or acreage or and range that contains many types of data. Unfortunately, many speak with certainty when they have only guesses about the specific instances included in the averages they observe. The devil *is* in the details, I'm guessing. *********************************************** The BEE-L mailing list is powered by L-Soft's renowned LISTSERV(R) list management software.
