Question

question 10 (6 points)
question: you want to compare the health outcomes of low - income fami
income families. you survey participants who will self - report their family
level. what type of study is this?

1. ecological
2. experimental
3. case - control
4. cross - sectional

Explanation:

• Ecological study: Focuses on group - level data (e.g., neighborhood - level, country - level) rather than individual - level self - reported data.
• Experimental study: Involves manipulation of an independent variable (e.g., giving a treatment to one group and a placebo to another). There is no mention of manipulation here.
• Case - Control study: Usually starts with identifying cases (with a disease or outcome) and controls (without) and then looks back at exposures. This is not the case here.
• Cross - sectional study: Collects data on variables (in this case, family income level and health outcomes) at a single point in time from a sample of the population. The self - reporting of family income level and comparison of health outcomes fit the cross - sectional design.

Answer:

1. Cross - sectional
