Question

22 mark for review dr. walsh gathers data on the number of teratogens pregnant women were exposed to in a large city and the number of weeks at which their babies were delivered. the correlation between the two measures obtained in this study would be graphically represented as which of the following? a bar graph b normal distribution c histogram d scatterplot

Explanation:

To determine the correct graph for representing the correlation between two variables (number of teratogens exposed to and weeks of delivery), we analyze each option:

• Option A (bar graph): Used to compare discrete categories, not for showing correlation between two continuous variables.
• Option B (normal distribution): Describes the distribution of a single variable, not a correlation between two variables.
• Option C (histogram): Displays the frequency distribution of a single variable, not a correlation.
• Option D (scatterplot): Specifically designed to show the relationship (correlation) between two quantitative variables by plotting individual data points.

Answer:

D. scatterplot
