Translation guide
The frequency of errors in a process, measurement, or transmission. In Japanese, the translation depends heavily on context: statistics, computing, quality control, or general use.
The proportion of incorrect results in a sample or experiment, such as in surveys, medical tests, or data analysis.
Standard term for error rate in statistics and measurement. Refers to the ratio of error to the true value.
この測定器の誤差率は0.5%以内です。
The error rate of this measuring instrument is within 0.5%.
Loanword from English, common in technical contexts like data transmission or computing, but also used in general statistics.
データ入力のエラー率を下げる必要があります。
We need to reduce the error rate of data entry.
The frequency of errors in digital communication, such as bit error rate or packet loss.
Specifically 'bit error rate' (BER), the standard term in digital communications.
この回線のビット誤り率は非常に低いです。
The bit error rate of this line is very low.
Common loanword for error rate in IT and networking, often used in technical documentation.
エラーレートが高すぎて通信が安定しません。
The error rate is too high, so the communication is unstable.
General term for error rate in information theory and coding; often used in academic papers.
The proportion of defective products or mistakes in a production process.
Standard term in manufacturing for defect rate or fraction defective.
今月の不良率は目標の1%を超えました。
This month's defect rate exceeded the target of 1%.
Colloquial term for mistake rate, often used in office work or manual processes.
入力ミス率を減らすためにチェック体制を強化します。
We will strengthen the checking system to reduce the input error rate.
The frequency of mistakes in any activity, like typing, speaking, or decision-making.
Natural Japanese phrase meaning 'proportion of mistakes'. Suitable for casual or non-technical contexts.
このテストでの間違いの割合は高かった。
The error rate on this test was high.
Means 'frequency of errors', often used in user interface design or human error analysis.
この操作ではエラーの頻度が上がります。
The error rate increases with this operation.
誤差率 (ごさりつ) is used for measurement or statistical error (deviation from true value). エラー率 (エラーりつ) is a general loanword for error rate, common in IT. 不良率 (ふりょうりつ) is specifically for defective items in manufacturing. Choose based on the field.
Directly translating 'error rate' as エラーレート or エラー率 may sound unnatural in non-technical conversation. Use 間違いの割合 or rephrase with よく間違える (make mistakes often) when appropriate.
誤り訂正符号によって誤り率を改善できます。
Error rate can be improved by error-correcting codes.
