Evaluating a Study on Parks and Obesity Rates

Medium Critical Reasoning Evaluating Data Arguments

A recent study published in a public health journal provides evidence that neighborhoods with more parks see a lower rate of obesity and related health issues.

The study examined data from over 500 neighborhoods across the country, concluding that those with at least one public park experienced a 15% lower obesity rate than those without. However, critics argue that the study does not account for other factors such as income levels, access to grocery stores, and cultural preferences that may also influence obesity rates.

Based on this information, which of the following statements best evaluates the argument made by the study?

The study's conclusion is valid because parks inherently promote physical activity.

The critics' concerns are unfounded because parks are the sole factor affecting obesity.

The presence of parks may correlate with lower obesity rates, but the study lacks controls for other important variables.

The study is flawed since obesity also depends heavily on genetic factors.
