The document summarizes a study of the nutritional content of various Starbucks beverages. It sampled different drink categories and analyzed the calories, fat, sugar, and protein levels. It found a high correlation between calories and fat, with calories explaining 58.24% of the fat content. The conclusion is that higher calorie drinks generally contain more fat, sugar, and protein. More research on different drink sizes, foods, beverages, and milk types could provide additional insights.

2. Our Project

 Hypothesis: the higher the calorie count, the higher
the amount of total fat, sugar, and protein
 We studied a variety of different Starbucks drinks
and their nutritional content
 Standard sample was a Grande
with 2% milk
 Our source of data was the Starbucks
nutritional guide distributed by the store

3. Sampling Design

 Stratified sampling – each drink represents a
different category and is treated as a separate
individual element
 Our study was unbiased because we sampled a
variety of Starbucks beverages

8. Regression Results

 Total fat vs. calories
 Correlation coefficient: .7632
 High correlation between fat and calories
 Coefficient of determination: .5824
 58.24% of calories are explained by fat content
 Slope: .0236 and y-intercept: -1.3089
 For every additional calorie = .02g of fat

9. Conclusions

 Higher the calories of each beverage, higher the fat,
sugar, and protein content
 Starbucks drinks do not specialize in
nutritional value
 Could conduct more research in various products –
different drink sizes, foods, additional beverages,
types of milk
