Step1: Recall range as measure of variation
The range is a measure of variation. For a box - and - whisker plot, the range is calculated as the difference between the maximum and minimum values.
Step2: Calculate range for start of season
For the "Começar" (start of the season) box - and - whisker plot, the minimum value is around 6 and the maximum value is around 16. The range $R_1=16 - 6=10$.
Step3: Calculate range for end of season
For the "Fim" (end of the season) box - and - whisker plot, the minimum value is around 6 and the maximum value is around 14. The range $R_2=14 - 6 = 8$.
Step4: Compare ranges
Since $R_1 = 10$ and $R_2=8$, and $10>8$, there was more variation at the start of the season.
