Below are sample questions representative of the exercises included on this worksheet and related 7.145 Bias and misleading graphs skill assessments:

Problem 1Difficulty: Mastery

A student uses one of these graphs to support a claim. Context: A school store tracks profit over eight weeks Data: Week 1 $82; Week 2 $75; Week 3 $80; Week 4 $78; Week 5 $84; Week 6 $79; Week 7 $81; Week 8 $77 Graph A: a line graph showing all eight weeks with a neutral title Graph B: a graph titled Profits Keep Climbing that shows only Weeks 4 and 5 Which answer correctly identifies the misleading graph, the feature that causes the misleading impression, and a fair corrected version?

AGraph B is misleading because the graph has too many data points; a corrected version would delete the least helpful points.

BNeither graph is misleading; choosing a short time range never changes a viewer's conclusion.

CGraph A is misleading because it includes the full time span; a corrected version would show only the part that supports the claim.

DGraph B is misleading because it cherry-picks the only short increase and ignores the rest of the data; a corrected version would show all eight weeks or state the graph is only about Weeks 4 and 5.

Solution & Explanation:The data should be shown without changing the viewer's impression. Graph B is misleading because it cherry-picks the only short increase and ignores the rest of the data. A fair correction would show all eight weeks or state the graph is only about Weeks 4 and 5. The full data fluctuate rather than steadily climb.

Problem 2Difficulty: Mastery

A student uses one of these graphs to support a claim. Context: Students choose a project format Data: Poster 40 votes; Slideshow 30 votes; Video 20 votes; Model 10 votes Graph A: a circle graph where Video and Model together take about half of the circle Graph B: a circle graph with sectors 40%, 30%, 20%, and 10% Which answer correctly identifies the misleading graph, the feature that causes the misleading impression, and a fair corrected version?

AGraph B is misleading because its sectors match the data too closely; a corrected version would make the largest sector look even larger.

BGraph A is misleading because a circle graph should not show percentages; a corrected version would remove all labels.

CGraph A is misleading because the sectors do not match the counts out of 100; a corrected version would draw each sector equal to its percent of the total.

DNeither graph is misleading; sector size does not need to match the part of the whole.

Solution & Explanation:The data should be shown without changing the viewer's impression. Graph A is misleading because the sectors do not match the counts out of 100. A fair correction would draw each sector equal to its percent of the total. Video plus Model should be 30%, not about 50%.

Problem 3Difficulty: Mastery

A student uses one of these graphs to support a claim. Context: A graph compares number of rainy days and cafeteria soup sales Data: Month 1: 2 rainy days and 180 soups; Month 2: 4 rainy days and 190 soups; Month 3: 6 rainy days and 200 soups Graph A: separate graphs with clear scales, or a single display that does not compare slopes from different units Graph B: a double-axis graph that scales rainy days 2-6 and soups 180-200 so both lines look equally steep Which answer correctly identifies the misleading graph, the feature that causes the misleading impression, and a fair corrected version?

ANeither graph is misleading; two different vertical scales cannot change the impression of a relationship.

BGraph B is misleading because the two different y-axes make changes in different units look equivalent; a corrected version would avoid comparing line steepness across different scales.

CGraph A is misleading because it avoids two vertical scales; a corrected version would add a second scale to make the lines overlap.

DGraph B is misleading because two data sets appear on one page; a corrected version would delete one data set.

Solution & Explanation:The data should be shown without changing the viewer's impression. Graph B is misleading because the two different y-axes make changes in different units look equivalent. A fair correction would avoid comparing line steepness across different scales. Rainy days triple, while soup sales increase by 20.
