1. The problem is to calculate the month-over-month percentage change for each metric from September (Q3) to October (Q4). 2. The formula for percentage change is: $$\text{Percentage Change} = \frac{\text{New Value} - \text{Old Value}}{\text{Old Value}} \times 100\%$$ 3. Calculate for each metric: - NMV: $$\frac{336,738 - 208,533}{208,533} \times 100 = \frac{128,205}{208,533} \times 100 \approx 61.48\%$$ - ORDERS: $$\frac{397 - 163}{163} \times 100 = \frac{234}{163} \times 100 \approx 143.56\%$$ - TRAFFIC: $$\frac{37,930 - 28,645}{28,645} \times 100 = \frac{9,285}{28,645} \times 100 \approx 32.42\%$$ - CR (Conversion Rate): $$\frac{1.05\% - 0.57\%}{0.57\%} \times 100 = \frac{0.48\%}{0.57\%} \times 100 \approx 84.21\%$$ - AOV (Average Order Value): $$\frac{848.21 - 1,279.34}{1,279.34} \times 100 = \frac{-431.13}{1,279.34} \times 100 \approx -33.72\%$$ - REFUND: $$\frac{0.15\% - 0.65\%}{0.65\%} \times 100 = \frac{-0.50\%}{0.65\%} \times 100 \approx -76.92\%$$ - AFTERSALE Rate: $$\frac{0.00\% - 0.01\%}{0.01\%} \times 100 = \frac{-0.01\%}{0.01\%} \times 100 = -100\%$$ 4. Final answers: - NMV: 61.48% - ORDERS: 143.56% - TRAFFIC: 32.42% - CR: 84.21% - AOV: -33.72% - REFUND: -76.92% - AFTERSALE Rate: -100% These values represent the month-over-month percentage change from September to October.
