How to say "average" in Japanese

Choosing the right word
  • 中ちゅうJLPT N3approx.Common
    nounTreats 'average' as the middle of a scale: grades, levels or sizes that are neither high nor low. Typical when rating results or ability as middling rather than computing a mean.
  • 平均へいきんJLPT N3approx.Common
    noun, suru verb, transitive verbThe default word for an average in the numerical sense: the mean of a set of figures. Use it for statistics, scores and other numbers, as in 'on average'.
    The temperature is above average this winter.
  • 並なみJLPT N1approx.Common
    no-adjectiveCovers 'average' in the sense of ordinary and unremarkable — on a level with what is usual, neither good nor bad. Typical when describing ability, results or quality as nothing special.
    これは並なみの能力のうりょくではない。↗
    This isn't any ordinary ability.
  • nounThe katakana borrowing of 'average', heard mainly in sports and statistics talk, as in a player's season average. For the general or mathematical sense, 平均 is the word to reach for.
  • 中等ちゅうとうCommon
    no-adjectiveReally a term for the middle rank or stage — secondary schooling, the middle class — not a way to call something average. For average grades or quality it is seldom the word you want.

Use 平均 for a calculated mean; 中 and 並 for middling grades or quality, 並 stressing ordinariness; 「アベレージ」 as the English loanword in sports and statistics; 中等 chiefly for a middle rank or secondary level, not for averages.
