Simple Question (basic statistics)

Is there a term for the distance from the data point furthest from the mean, to the mean? For example, if my data set is: [3, 4, 5, 6, 6, 7, 8, 8, 9, 10] then mean = 6.6 The data point furthest from mean is 3, so: 6.6 -3 = 3.6 This is close to half the range, but not quite…certainly I’m not the only...

Birthday Problem (variation)

Someone made a claim about birthdays that made me think of the well-known birthday problem. I wanted to compute the probability but was unable to. I'd appreciate your help.

I think I might have found the answer. http://www.agu.org/journals/ABS/1982/RG020i003p00457.shtml The review claims this research resolves the time problem.

What one needs to do this effectively is a modified "auto-belay". Otherwise as soon as he flaps his wings the effect the bricks are having on him will change. Ok..more to the point.. it won't be consistant like atmospheric pressure and gravity. With the autobelay, one simply adjusts the s...

Obviously the bricks need to be suspended off the ground before flapping his wings for this to work. The beginning height of the bricks would then be the maximum attainable altitude (once he get that high, the bricks will touch the ground and no longer providing 91% of the lift). So this can be done...
