An October 2025 technique guide distills 资料分析 to three base formulas: 增长量 = 现期量 − 基期量, 增长率 = 增长量 ÷ 基期量, 比重 = 部分量 ÷ 整体量. Everything else is estimation. 截位直除 truncates division to the option spread, 百化分 turns 16.7% into 1/6, and a part growing faster than the whole gains share with no arithmetic at all.
推荐原因：You asked about 资料分析 speed techniques this morning. This is the drill-down past the overview: what to memorize, what to estimate, and which questions need no calculation at all.
关键数据：
- 增长量 shortcut：r ≈ 1/n → 现期量 ÷ (n+1)
- 基期量 shortcut：|r| ≤ 5% → 现期量 × (1 − r)
