SUMMARY

The discussion centers on the calculation of percentage discrepancy in data analysis, specifically addressing the scenario where the observed value is zero. The formula for percentage discrepancy is defined as |observed value - measured value| / measured value x 100%. In the case presented, with an observed value of 0.000 and a measured value of 0.0008, the percentage discrepancy results in 100%. This raises questions about the implications of having a zero observed value in the calculation.

PREREQUISITES
  • Understanding of basic mathematical concepts, particularly absolute values.
  • Familiarity with percentage calculations and their significance in data analysis.
  • Knowledge of data measurement techniques and their implications.
  • Basic statistics, including concepts of observed vs. measured values.
NEXT STEPS
  • Research the implications of zero values in statistical calculations.
  • Learn about alternative methods for handling zero values in data analysis.
  • Explore the concept of relative error and its application in data measurement.
  • Investigate best practices for reporting percentage discrepancies in scientific research.
USEFUL FOR

Data analysts, statisticians, researchers, and students involved in quantitative analysis who need to understand the nuances of percentage discrepancy calculations.

Homework Statement



Hi guys, I need help with percentage discrepancy.


Homework Equations



I understand that percentage discrepancy is given by |observed value - measured value| /
measured value x100%

where || is the absolute value.

The Attempt at a Solution



However, one of my observed value is 0.000 and measure value is 0.0008
Although the difference is very small, because of the zero observed value, my percentage discrepancy calculated to be 100%. Is there an assumption in the formula used that the observed value cannot be = to zero?

Or should I keep percentage discrepancy to be 100% in this case?

Thanks for the help.
