Measured or given value being tested

True or correct value

Derive observed value and accurate value

Subtract observed from accurate, take absolute value

Divide error by accurate value

Multiply by $100$

$\frac{Error}{Accurate\space Value}$

$(Relative\space Error) \cdot 100$

$|0.8-1|=0.2$

$\frac{1}{4}$ or $0.25$

$25\%$
