3B
Invent a sharable (replicable) measurement process to quantify a characteristic of the sample.
"In order to find the best guess, I count from the lowest to the highest and from the highest to the lowest at the same time. If I have an odd total number of data, the point where the two counting methods meet will be my best guess. If I have an even total number, the average of the two last numbers of my two counting methods will be the best guess."
