1.
margin of error; error range; error tolerance
The range within which measured or estimated values are considered to deviate from the true value, treated as acceptable or expected variation. Used in statistics, polling, science, and engineering, and also colloquially to mean 'close enough' or 'negligible difference'.
誤差範囲内だ。
It's within the margin of error.
調査の誤差範囲は前後三パーセントです。
The margin of error for the survey is plus or minus three percent.
二つの測定結果の差は誤差範囲内で、有意な違いとは言えない。
The difference between the two measurements is within the margin of error and cannot be called statistically significant.
Compound of 誤差 ('margin of error, discrepancy') + 範囲 ('range, scope'). Used in both technical writing (statistics, science, manufacturing) and general conversation.
In casual speech, 誤差範囲 often means 'a negligible difference' — something not worth worrying about.
COMMON COLLOCATIONS:
- 誤差範囲内: within the margin of error
- 誤差範囲を超える: to exceed the margin of error
- 誤差範囲を示す: to indicate the margin of error
- 許容誤差範囲: allowable margin of error; tolerance
- 前後数パーセントの誤差範囲: a margin of error of a few percent either way
RELATED TERMS:
- 誤差: error; discrepancy — the amount of deviation itself
- 範囲: range, scope
- 許容範囲: acceptable range; tolerance range
- 標準偏差: standard deviation — a statistical measure of spread
- 有意差: significant difference — contrasts with 誤差範囲内
USAGE:
- Formal/technical: precise numerical ranges in reports, research papers, and polls.
- Colloquial: dismissing a small difference — 'そんなの誤差範囲だよ' ('That's just within the margin of error' = 'That difference doesn't matter').
