Ordering a list SQL or Excel -
i have simple task @ work daily , think can done help. there table single column "pc name". have divide list of pc's waves.
wave 1 : 2% wave 2: 3% wave 3: 25% wave 4: 45% wave 5: 25%
so copy list of pc's excel , add column named "wave assign". example if list 100 pc's first 2 pc's assign wave 1
, 3 pcs towave 2
, 25 pcs wave 3
, on.
i need way automate since takes me long manually. doesn't matter if there small change in % in order round number of pcs in each wave.
assuming list in columna starting in row1:
=vlookup(rows(a$1:a1)/counta(a:a),warray,2)
in row1 , copied down should work, provided lookup array of following kind created:
and named warray
.
in case list shorter 100 have added .002 'logical' breakpoints (cumulative proportions) not minority waves rounded down such that, @ 50 items, wave 1 not feature (and hence stand out rather more approximation in larger group).
