How to determine the values from a list?
 

Referring to the post in General Question

Does anyone have any idea on how to determine the values under following
conditions?
Given a list of numbers sorted by ascending order from top to bottom under
column A, I would like to determine the minimum range within this list
covering 50% of total numbers, and return the smallest number within the
range in cell B1 and the largest number within the range in cell B2.
Does anyone have any suggestions?
Thank you in advance
Eric

How to determine the values from a list?
 

More description on question

If the list contains 10 numbers, then I need to select 5 numbers covering
the minimum range, such as following example with 10 numbers, and I need to
select 50% of 10 = 5 numbers covering minimum ranges.

1,3,21,40,41,42,43,44,88,99

In this case, I should select 40,41,42,43,44
41 returns in cell B1
44 returns in cell B2

Thank for any suggestions
