Why each option
To determine if the sugar content has generally increased over the years, the mean is the most appropriate descriptive statistic to track changes in average sugar levels.
Frequency would show how often certain sugar levels occur but doesn't directly indicate an overall increase or decrease in the sugar content itself over time.
Percent change measures the relative change between two values but is typically calculated after determining the values (like means) for comparison, not as the primary descriptive statistic to show an increase.
