Quizplus · Accepted Answer

The relative error is calculated as the difference between the measured value and the true value, divided by the true value. Here, the true value is 2 scoops (recommended by the manufacturer), and the measured value is 3 scoops (used by the aficionado). The difference is 1 scoop. So, the relative error is 1 scoop / 2 scoops = 0.5 or 50%.
