statistic
📊 统 = unify/govern + 计 = count/calculate
统 means to unify or bring together under one system; 计 means to count or calculate. Together: unified counting — the systematic gathering of numbers, i.e. statistics.
计 — speech radical 讠 (言) + ten 十
计 is a semantic compound: 言 'speech/words' plus 十 'ten', suggesting counting or reckoning aloud. The original sense was to calculate or tally numbers, which extended to 'plan, scheme, plot' — any kind of mental reckoning. Modern uses like 计算 (calculate) and 计划 (plan) preserve both threads.
