A statistical term composed of 中央(ちゅうおう) (center; middle) and () (value). The 中央値(ちゅうおうち) is frequently used in news and economic reporting because, unlike the 平均値(へいきんち) (mean/average), it is not skewed by extremely high or low values. This makes it especially useful for income, housing prices, and other data with uneven distributions.
