CI (신뢰구간)

통계

If the score were measured again, there's a 95% chance it lands in this range.

Standard definition

A z-score-based [low, high] interval.

FAQ

If the confidence interval is wide, should I trust the score less?
A wider interval means the score has more room to shift if it were measured again under the same conditions; a narrow one signals a steadier score. Don't read the single number alone — the width tells you how solid the signal is.
Does 95% mean the score is 95% correct?
No. It's not the odds the score is right — it's a statistical way of saying that if you measured again, the result would fall inside this range about 95% of the time. It says nothing about predicting the future.
