We've already had some math errors crop up in the data collection thread. Unfortunately, trying to provide a running total with each post doesn't seem to be working. I put the data into a spreadsheet and the stats including post 78:

73 riders
1498 total miles (round trip)
Maximum: 56
Average: 20.81
Median: 19.5
Mode: 21
Minimum: 4

I'll work on maintaining the spreadsheet for a few days, maybe a week so we can get some good statistics. Maybe that college course I took in biostatistics is useful after all.

Definitions for those who are interested:

Average = arithmetic mean.
Median = The median is the number in the middle of a set of numbers; that is, half the numbers have values that are greater than the median, and half have values that are less.
Mode = The most frequently occurring, or repetitive, value in an array or range of data.
