IB Chemistry, IB Biology on uncertainty calculation, random error, standard deviation and error analysis

IB Chemistry, IB Biology on Uncertainty Error Calculation, Random vs Systematic error, Precision vs Accuracy

Conclusion and keywords from slides:
  • Addition and Subtraction - Add absolute uncertainties
  • Multiplication and Division - Add percentage uncertainties
  • Uncertainty calculation for Rate of reaction and Conc of solution can be calculated using - % Uncertainty Method or  Max/Min Method
  • Accuracy vs Precision
  • Random Error vs Systematic error
