Hi Toon,
Not certain this will do exactly what you want:
No S (No is a numbering of your sample S, hidden 3 tru 98)
1 1 (S is your sample result, used 1 to 100 for simplicity, obvious yours
2 2 is differant)
99 99
100 100

Random1 98 =VLOOKUP(RANDBETWEEN(1,100),$A$1:$B$101,2,FALSE)
Random2 47
Random99 84
Random100 69 =VLOOKUP(RANDBETWEEN(1,100),$A$1:$B$101,2,FALSE)
(The Vlookup pulls down from above your sample data, why you needed to
number the sample)
Median 56.5 =MEDIAN(B103:B203)
Variance 849.2690909 =VAR(B103:B202)

Hope this helps and does what you want.
