how does common hk ppls do statistic...
undoubtedly, the most popular method is the Billboard method...
the origin of this method is unknown...
although there is generally a lack of statisticians research in this specific area...
but it remains one of the favourite ways for ppls to generate a representative sample...
this method can be applied to many areas, but it does have its limitations...
it is mainly used for getting a sample of the population and find calculating the statistics needed...
the Billboard method is understood to be taught by older generation to the younger generation...
education of such in school is almost unheard of...
but yet it remains a robust and trusted way to be representative of the matter depending on the person who computed it...
A Breakdown of the Billboard method
in the model of the Billboard method, it does not explicitly describe the population...
it does not define the size of the population, but there is a common tolerance of the range which each individual can make assumption...
for the simplistics, the population can be assumed to be 10...
as this assumption would simplify the calculation to find the percentage of the groups...
but in general, the size of the population is assumed to be the number of ppls on a normal (normal as in distribution) street on a normal (again, normal as in distribution) day...
there is another crucial detail of the model...
it is important to remember to include the movement of the ppls in the populating the normal street...
the "fluid dynamics" of the population in the end will affect greatly the overall result...
the "fluid dynamics" of ppls in itself is another massive field of research which could sustain many thesis...
and it is also an art that, i believe, many are not competent at...
---------------------------------------------------------------------------------------------------------------------------------------
an example merely for demonstration purpose, take MK...
if ppls can themselves calculate the optimum distribution of the population...
then there wouldn't be such a overcrowding in MK, resulting in a very low fluidity on the normal street...
but we would not go into details in the field of population fluid dynamics here...
it maybe a topic which we could revisit in the future...
---------------------------------------------------------------------------------------------------------------------------------------
back to the Billboard method...
to be continued...
