Definition
次数 (cì shù) is a noun meaning 'number of times' or 'frequency' — it counts how many times an event occurs (e.g., 迟到次数 'number of times late'). Unlike 度 (dù), which is a measure word for occasions (e.g., 一次 'one time'), 次数 is a noun that can be modified and used in statistics. It differs from 频率 (pín lǜ), which refers to the rate or frequency per unit time (e.g., 高频率 'high frequency'). In math, 次数 also means 'power' or 'degree' of a polynomial.
