Under "Statistical Analysis" the "Weighted-Mean" tag expected age is 72. Under "Mathematics" the "Non-Standard Analysis" tag expected age is 19. I suspect samples of 1 for each of these tags.
This is fun to look at but I wouldn't base any conclusions on these averages. Providing histograms for each tag along with some summary statistics such as sample size, min, max, and median would give a lot more transparency into the dataset.
