2. Research Question
Do the nutritional factors in chips, such as
total fat, carbohydrates and protein
determine the amount of calories in chips?

3. Hypothesis
 We believe that the main nutritional
factors, such as total fat, carbohydrates and
protein will be directly proportional to the
caloric content of the chips.

4. Research
 Compiled nutritional facts of various types of
chips
 Compared Total Fat, Protein and
Popular Types of Chips
