Re: How to test whether a number is harmony with a given set or not?



Well let me put it this way,

Two sets of numerical values according their distributions(unknown),
and a new numerical value. How can you say whether it should belong to
the first set or the second one?

If we plot all the values into a one-dimensional axis, then we can find
a middle point which separate values from two sets clearly(enough).
Then if the new value is to the right of this point, it may belong to
one set while if it is to the left of the point it may belong to the
other. This is all the assumption. For example,

Set one = {0, 9, 5, 10, 8, 55}
Set one = {90, 14, 25, 67,19}.
Then 6 may belong to set one but 54 may belong to set two.

Formal algorithm from statistics is what I am looking for.

Thank you very much.
