Carane nganggo Kalkulator persen kesalahan
Apa sing dietung lan kapan nganggo
Mbandhingake nilai sing diukur utawa dikira karo nilai sing bener utawa ditampa lan nyatakake bedane minangka persentase. Digunakake ing laboratorium ilmu, pamriksan teknik lan ramalan.
Carane nganggo, langkah demi langkah
- Lebokna nilai sing panjenengan ukur.
- Lebokna nilai sing bener utawa ditampa.
- Waca persen kesalahan, kesalahan absolut lan kesalahan bertanda.
Tegese saben input
- Measured Nilai – The experimental, observed utawa estimated Asil.
- True Nilai – The theoretical utawa accepted Nilai. It cannot be zero.
Carane maca asile
- Persen Kesalahan – The size of the error as a percentage of the true value.
- Signed Kesalahan – Positive if you measured too high, negative if too low.
- Persen difference – Compares two values with neither one treated as correct.
Rumus
Percent error = |measured − true| ÷ |true| × 100. Percent difference = |a − b| ÷ ((|a| + |b|) ÷ 2) × 100.
Conto petungan
A student measures gravitational acceleration as 9.6 m/s² when the accepted value is 9.81. The absolute error is 0.21, so the percent error is 0.21 ÷ 9.81 × 100 = 2.141%, and the signed error is −2.141% because the measurement is low.
Asumsi lan watesan
- The true value yaiku known lan non-zero.
- Unit must match.
Kesalahan umum
- Dividing by the measured Nilai instead the true Nilai.
- Using Persen Kesalahan when there yaiku no accepted Nilai.
Pitakonan sing kerep ditakokake
Apa persen kesalahan bisa negatif?
Definisi standar nganggo nilai absolut, mula positif. Kesalahan bertanda nuduhake arahe.
Kepriye yen nilai sing bener iku nol?
Persen kesalahan ora bisa ditemtokake. Gunakake kesalahan absolut.
