The formula to calculate the Average Seasonal Variation (ASV) is:
\[ \text{ASV} = \frac{\text{TSV}}{\text{N}} \]
Where:
Let's say the total seasonal variation (TSV) is 120 units and the number of seasons (N) is 4. Using the formula:
\[ \text{ASV} = \frac{120}{4} = 30 \, \text{units} \]
So, the average seasonal variation is 30 units.
