topic
, Exploratory: Explore the barriers to eating healthy foods for
Hispanic women in an urban community
Descriptive: Examine the availability and price of low-fat and
What are the purposes of higher-fat milk in stores across the United States

Comparing Quantitative and
variables
Qualitative Research
Qualitative
- no hypotheses
- no statistics (very few numbers)
