Definisi
Rentang di atas dan di bawah nilai yang diukur atau diestimasi di mana nilai sebenarnya diharapkan berada, biasanya dinyatakan pada tingkat kepercayaan tertentu.
Penjelasan
A poll reporting 52% ± 3% has an error margin of 3 percentage points at 95% confidence, meaning the true value likely lies between 49% and 55%. In physical measurements, a laboratory scale might report 125.4 ± 0.1 g, indicating the true mass is within 0.08% of the reading. Error margins quantify uncertainty without hiding it.
