Why in the world do you want to know the modal and median instead of the average???
Modal is the data that repeats the most and obviously you have to take your times and speed often to do that. So if you stop 30 times you have 30 speeds between stops... pick the one that repeats the most, thats your modal speed.
The median is the value that is just in the middle... same problem, you have to stop and take your times and speeds in intervals, do the math and pick the data that is just in the middle. If you stop 20 times... calculate the speed between each of those stops, put them in order at the end of the trip and pick the data that is number 10... done.
The modal speed and the median speed might not be the same obviously either way I dont understand why you want to do this tho... well there you have it... good luck.
is this thing on?
im just training for a century and want to know these, so i can correlate it to my heart rate per zone.
If you had a garmin / powertap or other such setup, you could pretty easily find the mode by having it record speed every second, and then look at your speed distribution graph after your ride. In fact let me look... the ride I just did. First I told it to remove all ZEROS. Otherwise that it is most common speed in my file. Then I need to tell it the BIN width. If I tell it to graph it per every MPH evenly, my mode is clearly 19mph. The average speed for this ride was 17mph, btw. Oh but if I tell it to break speed down to the tenth of the MPH, the mode was 17.2. So there. Totally useless metric, I would say.
I prefer Ionian modal speed but occasionally will use Phrygian modal speed.
what do you mean modal? average modal over time? or modal like that dragon-beast with the seven heads from Modal like Mothra aka Mothra vs. Godzilla?

Histogram in WKO would make this easy - if you care
You want modal and median speeds so that you can virtualize the century ride and vary specific parameters? Good idea.
edited: it piques my interest because "modal" has some problems in this context, and I think it requires more of a clustering analysis than simple statistics. Clustering is difficult but interesting. Intuitively some application of particle swarm optimization may be effective.

i prefer the Fibonacci method of riding a century, but sometimes the golden rectangle is the best option.
*sigh*
I'm developing a new software package for cycling and thought I had all the bases covered -- FTP, IF and such. Now I'm hearing about things like "Superlocrian modal speed", "hypophrygian" and others I can't begin to pronounce. Is there a new book or web site I'm not aware of?
