Hi together

We are working at a manmade ecosystem. In this system we are locking
for several parameter like number of cell counts or different
enzymatic activities.
Does anyone knew a method how I can calculate if two measurements
differ in a significant way from each other taking a number of
determinations as basis.

Example: Number of cell counts per ml:
Measurement		cell counts
1			4830000
2			2820000
3			2250000
4			5000000
5			13000000
6			9750000
7			14500000
8			8670000
9			667000
10			792000
11			1950000
12			93700
13			867000
14			762000

Does the results of nr.: 13 and 14 differ in a significant way, or
not???

Thanks for helping
