Demonstrate concretely, pictorially, and symbolically an understanding of limitations of measuring instruments including:
  • precision
  • accuracy
  • uncertainty
  • tolerance.

[C, PS, R, T, V]

Indicators for this outcome

Explain, using concrete models and pictorial representations, the difference between precision and accuracy.


Analyze given contexts to generalize and explain why:

  • a certain degree of precision is required
  • a certain degree of accuracy is required.


Compare the degree of accuracy of two or more given instruments used to measure the same attribute.


Relate the degree (margin) of accuracy to the uncertainty of a given measure.


Analyze and justify the degree of precision and accuracy required in contextual problems.


Analyze given contexts to calculate maximum and minimum values, using a given degree (range) of tolerance.


Compare and describe, using examples, the limitations of measuring instruments used in a specific trade or industry, (e.g., tape measure versus Vernier caliper).


Create and solve situational questions that involve precision, accuracy, or tolerance, and explain the reasoning and the strategy used to arrive at the solution.
