Hass avocados are globally consumed, nutrient-rich fruits. While current analyses mainly benefit the industry, there is a need for research focused on consumer advantages. Understanding the statistical relationships between the physical characteristics of avocados, particularly pulp content, can help consumers make better purchasing decisions. This study examines the physical attributes of Hass avocados and their relationship with fruit weight over a wide range of weights. Our findings reveal a strong correlation between the absolute weight of the avocado and its pulp weight (R² = 0.9878). The pulp proportion remains nearly constant across different avocado weights. This constancy is explained by the compensatory relationship between the seed and peel weights, shown by the quasi-mirror-like inverse regression lines (similar coefficients with opposite signs). The regression coefficient for pulp proportion as a function of fruit weight is 10⁻⁵, indicating a marginal increase in pulp mass with heavier avocados. Thus, while we can recommend purchasing larger Hass avocados based on this data, price considerations are crucial. In Chile, for instance, larger Hass avocados are more expensive, almost double the price, and the slight increase in pulp content does not justify the price difference.
