Discussion Overview

The discussion revolves around the methods for adding, subtracting, multiplying, and dividing uncertainties in measurements. Participants explore how to estimate errors when performing calculations with measured values, particularly in the context of propagation of uncertainty.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant requests clarification on how to handle uncertainties in measurements, specifically asking for methods to add, subtract, multiply, and divide these uncertainties.
  • Another participant seeks to clarify whether the question pertains to estimating the error in a function based on the errors in its variables.
  • A participant provides examples of measurement errors, indicating specific values and their associated uncertainties.
  • Reference to external material on the propagation of uncertainty is suggested, noting that for uncorrelated variables, covariances and correlation factors are zero.

Areas of Agreement / Disagreement

The discussion does not reach a consensus, as participants express varying levels of understanding and interpretation of the initial question regarding uncertainties.

Contextual Notes

There are limitations in the clarity of the initial question, and assumptions about the nature of the variables and their correlations are not fully explored.

Can someone show me how to add, subtract, multiply and divide uncertainties in measurement.

I'm not sure I understand your question. Do you mean something like given errors in measuring a and b estimate the error in calculating some function f(a,b)? Or something else?
 


errors in measurement like 0.06 plus and minus 5% and 0.09 plus and minus 3%
