Numeracy

Calculating instrument error

No items found.

Practise calculating error from single measurements and multiple readings. Identify which equation to use when working with calculations involving addition, subtraction, multiplication or division and apply this to various scientific contexts.

Learning outcomes

  • Calculate percent error in measurements and interpret its significance in experimental contexts.
  • Evaluate the impact of error on the validity and reliability of experimental results.
  • Evaluate different glassware in terms of their precision, using evidence from error calculations.
  • Apply error propagation rules to determine the cumulative effect of errors from multiple sources in an experiment.

"I find Smart Worksheets a lot less stressful than full written lab reports and much easier to cope with in terms of my ADHD and anxiety. I feel that they allow people with learning difficulties to be assessed in a way that is more beneficial to our needs, and help us get the marks we may have lost out on in assignments with large chunks of writing, or take a lot longer to do."
