Question

A reputable scholar publishes a study demonstrating that in neighborhoods with grocery stores that carry less fresh produce, people eat fewer healthy foods relative to neighborhoods with grocery stores that carry more fresh produce. In light of this study, public health activists start a campaign to convince grocery stores to stock more fresh produce. Is it correct to infer from this study that if grocery stores stock more fresh produce, the surrounding households will eat healthier diets? Why or why not?

Answer 1

In the given scenario, the dependent variable is "people eating healthy foods", now this might depend on a lot of factors and one among them is the independent variable "grocery stores carrying fresh produce". so what we can infer from this relation is, yes, people eating healthy foods is impacted by the produce kept by grocery stores, but we are not unsure upto what extent the impact is, therefore we can't generalize and say if grocery stores have fresh produce, neighborhoods eat healthy foods.
