How does a histogram constructed from a data set that excludes >85% of the total possible cases reveal JACK?!?!
Know what? It doesn't...

Know what? It doesn't...SURE it can be and is meaningful - IF a random selection are 'culled' from the group - or a process excludes a certain random (BASED on no criteria which otherwise skew the result) part of the population from consideration in the first place.
It's called 'sampling' and it's done all the time in a multitude of fields from semiconductors testing to medicine ...

You'll *also* note that this was a histogram based on "date of onset" - this would *naturally* cull a certain number of samples from this chart (those *not* possessing an 'onset date') - and it would most likely be about as random a factor as one could find, too, to 'cull' with.
