Statistical analysis of titration methods

[Lucas Souza]

Hi, guys 

How are you?

So, i'm doing a experiment where i'm testing two titration methods, the tube test and the column agglutination technique.

Now i have to analyze to know if they have statistical difference and what is the correlacion of the two methods, but I found it difficult to decide which statistical test to use.

Do you have any thoughts on which statistical test I should use? T teste? Pearson?

Below is the table with the samples and their endpoints, for example:

PLASMA	TUBE A	GEL A	TUBE B	GEL B
1	128	256	32	64
2	32	32	64	64
3	64	64	32	16
4	64	32	32	16
5	64	32	64	32
6	32	32	32	16
7	64	32	64	32
8	32	32	32	32
9	32	32	32	16
10	64	32	32	32
11	64	32	64	16
12	128	64	128	64
13	64	32	64	32
14	32	16	32	16
15	64	32	128	64
16	128	64	32	16
17	128	64	64	32
18	64	64	16	8
19	64	64	64	32
20	32	16	32	16

 

Thank you guys.

I'd use measurement of uncertainty as per ISO 15189
