SUMMARY

The discussion focuses on calculating the average of two percentages with their associated uncertainties. The average of 53.3% and 65.8% is determined to be 59.55%. When combining the uncertainties of 1% each, the total uncertainty is calculated as +/- 2%, which is then divided by 2 to yield a final uncertainty of +/- 1%. This method ensures accurate representation of the uncertainty in the average calculation.

PREREQUISITES
  • Understanding of basic statistics, specifically averaging techniques.
  • Familiarity with percentage calculations and their uncertainties.
  • Knowledge of how to combine uncertainties in measurements.
  • Ability to perform arithmetic operations with percentages.
NEXT STEPS
  • Research "Combining uncertainties in measurements" for deeper insights.
  • Learn about "Propagation of uncertainty" in statistical calculations.
  • Explore "Weighted averages" for scenarios with different uncertainties.
  • Study "Error analysis in experimental physics" for practical applications.
USEFUL FOR

Students in physics or engineering, statisticians, and anyone involved in data analysis requiring accurate average calculations with uncertainties.

Homework Statement


I currently want to add 2 percent each with a relative uncertainty together:
\frac{53.3\% +/- 1\% + 65.8\% +/- 1\%}{2}

I'm not sure how I can add the percentage uncertainty.

Homework Equations





The Attempt at a Solution


I've concluded that the average is 59.55%, however I'm unsure about how to handling adding the percentage uncertainty.

When you are adding and subtracting, you add the uncertainties together. In this case you get +/- 2%. Don't forget to divide this by 2 as well.
