## VB0182

In which panel do most points follow a broad curved rise-and-fall pattern that the blue straight line misses, rather than the main mismatch being one isolated outlier?

Rules: Judge the arrangement of most orange points. A single high or far-right point is not a broad curved pattern. Use panel positions, not an assumption that equal-looking blue lines imply equal data shapes.

## VB0183

Compared with the unshaded share of the middle pie, how does the unshaded share of the result pie on the right differ?

Rules: All circles represent the same whole. White is unshaded and grey is shaded. Use the radial partitions to read fractions; do not compare the total size of the circles on the page.

## VB0184

Using the chart, how does the share of noncitizens in Gwinnett County compare with the share in Georgia?

Rules: The bars show citizenship, not noncitizenship. Treat the noncitizen share as100% minus the displayed citizenship share. Compare percentage points and choose the nearest offered magnitude. This concerns the pictured2015 chart, not current populations.

## VB0185

Which comparison correctly combines a higher median with a smaller interquartile range?

Rules: The thick line inside each box is its median. The box height, not the full whisker span, is the interquartile range. Read both properties before choosing.

## VB0193

Approximately what fraction of the states are represented by the first three histogram bins combined?

Rules: The vertical axis counts states, not land area. Add the counts in the first three adjacent bins, then compare with the total count across every nonempty bin. Choose the nearest offered percentage.
