I can think of a couple scenarios where they might, though: - If trailing zeros were cut off with no regard for measurement accuracy (e.g., writing 14 instead of 14.0), then obviously no numbers would end in zero. - If insignificant trailing zeros were counted (e.g., saying 1800 ± 100 ends in 0 instead of 8), then zero would be more frequent in many data sets. - If values are rounded to anything other than one times the LSD, the distribution will be uneven (e.g., temperatures rounded to the nearest 0.5° F will always end in 0 or 5). Thanks from Loren
