The max deviation (non linearity ) of a system

Click For Summary

Homework Help Overview

The discussion revolves around estimating the maximum deviation (non-linearity) of a system based on a plot of energy deviation versus true energy from a germanium lab experiment.

Discussion Character

  • Exploratory, Assumption checking, Conceptual clarification

Approaches and Questions Raised

  • Participants are questioning the definition of "maximal deviation" and exploring methods to quantify deviations in the data. One participant mentions using linear lines through specific points to find differences, while another notes the data appears linear but lacks a clear method for quantifying deviations.

Discussion Status

The discussion is ongoing, with participants seeking clarification on definitions and methods. Some guidance has been offered regarding potential approaches, but no consensus or resolution has been reached.

Contextual Notes

There is a mention of a plot that is referenced but not provided, and the discussion includes uncertainty about how to proceed with the analysis of the data.

Hi,

I have a question from my germanium lab, which is how to estimate the max deviation (non linearity ) of a system.
I plot the relation between the deviation of the energy as a function of true energy and got this ( see pic), but didn't know what to do next.

How is "maximal deviation" defined?

I moved the thread to the homework section.

I moved the thread to the homework section.
The highest deviation which in the plot is (1400,610)
As i understood from one of my partners he used a linear line through the highest point and another line through the lowest one, then he found the difference between these two equations.
which i didn't know how to do.
 
Well, the data points look quite linear, so you can describe your data well. Then you look for some deviations, but with an unknown way to quantify those.
