MA5-MAG-C-01 solves measurement problems by using scientific notation to represent numbers and rounding to a given number of significant figuresContent dot points
Each dot point has its own page with resources matched to it.
Identify and describe very small and very large measurements
- Identify and describe the meaning of common prefixes, such as milli, centi and kilo
- Establish the meaning of prefixes for very small or very large measurement units
Find absolute and percentage error
- Determine the precision of a measuring instrument by finding the smallest division on the instrument
- Find the absolute error of measuring instruments (absoluteerror = 1/2 × precision) 2 resources
- Calculate the percentage error of a given measurement by applying the formula: percentageerror = (absoluteerror)/(measurement) × 100%
