calculate and interpret absolute, relative and percentage errors in measurements, recognising that all measurements are estimates

Elaborations

AC9M9M04_E1 - investigating error as a percentage of the exact value; for example, comparing an estimation of the number of people expected to come to an event by subtracting the actual number that turned up to give an error, then converting this into a percentage error
AC9M9M04_E2 - using absolute value in a percentage error formula; considering when they would use the absolute value and when they would not, depending upon the context
AC9M9M04_E3 - calculating the percentage errors in expected budgets to actual expenditure
AC9M9M04_E4 - estimating the accuracy of measurements in practical contexts and giving suitable lower and upper bounds for measurement values
