What's inside
- Using the average percentage method, calculate the seasonal index for Q1 from the table (round to 1 decimal place). The seasonal indices are then scaled so they average 100.
- Using the average percentage method, calculate the seasonal index for Q2 from the table (round to 1 decimal place). The seasonal indices are then scaled so they average 100.
- Using the average percentage method, calculate the seasonal index for Q3 from the table (round to 1 decimal place). The seasonal indices are then scaled so they average 100.
- Using the average percentage method, calculate the seasonal index for Q4 from the table (round to 1 decimal place). The seasonal indices are then scaled so they average 100.
- The seasonal index for Q3 is 142. Interpret what this tells you about Q3 compared with an average quarter.
- The actual Q3 figure in Year 1 was 87 units. Using the Q3 seasonal index of 142, calculate the deseasonalised figure (to 1 decimal place). Deseasonalised value = actual value divided by (index / 100).
