The percentage of the error of several signals

Hello! I have 6 signals. Example 1-200 201 193 2-44 45 41 3-16 17 14 4-1 1 0 5-55 58 45 6-900 920 894; I need to compare all these signals at the same time, and calculate the error, nowhere can I find how to do this. All signals depend on each other. It is necessary to compare them as far as they do not coincide with the signal No. 6.

[Mario Chiappelli]

The equation for percent error is ((actual - theoretical)/theoretical)*100.

Or what you probably want is a measure of uncertainty since you don't have any theoretical values to use. Here is the documentation for uncertainty, it can get a tad complicated.
