平均 (píng jūn) means 'average' or 'mean' — the central value obtained by dividing the sum of a set of numbers by how many numbers there are. The character 平 (píng) means 'level', 'even', or 'balanced', and 均 (jūn) means 'equal' or 'uniform'; together, they express the idea of distributing values evenly across a group. It functions both as a noun (e.g., the average) and as an adjective (e.g., average temperature).

This word is widely used in statistics, education, daily life, and media — for instance, when discussing average income, test scores, rainfall, or commute times. It often appears with measure words like 'rate', 'score', or 'time', and commonly follows verbs like 'is', 'calculate', or 'reach'. Unlike colloquial alternatives like '大概' (roughly), 平均 carries a precise, quantitative nuance and is standard in formal and informal contexts alike.
