蒙蒙, statistics rules

there are always something deviating from the center, the mean, the average,

especially for a big set of samples,

but the only scientific, and often sensible too, way is to look at the overall picture,

this is not to deny the issues, but just to assign them with appropriate weight,

as someone suggested, many times the sky is cloudy because our eyes are cloudy,

not to mention that, a frog could become really knowledgeable about the world if he can manage to get beyond the well,

we are all, to various degree, prisoner to our own experiences,

but we live to keep expanding our horizons, don't we?
