D. All of the above
Explanation
Graphs can be misleading because they may use varying scales, which can distort the visual representation of data and make comparisons difficult. They may also have suggestive captions that bias the interpretation of the information presented. Additionally, graphs may be based on small samples, which can lead to inaccurate conclusions or generalizations about the data. Therefore, all of these factors contribute to the potential for graphs to be misleading.

Explanation
The media can influence a person's opinion by using graphs and changing the vertical scale, using data taken over a short period of time, and using data taken from a small sample size. However, altering the data to make a better point is not a true statement because it is unethical and goes against journalistic integrity.

### The following graph shows the number of points a hockey team had over four seasons. The graph is misleading because

• A.

It does not include years before 1999

• B.

It does not indicate the number of games

• C.

The vertical scale exaggerates the number of points in 2002

• D.

It only shows the points for one team

C. The vertical scale exaggerates the number of points in 2002
Explanation
The graph is misleading because the vertical scale exaggerates the number of points in 2002. This means that the height of the bar representing the number of points in 2002 is not proportional to the actual number of points. This can lead to a misinterpretation of the data, making it seem like the team had more points in 2002 than they actually did.

• D.

The greatest increase in tuition occurred in 2001

A. The tuition increased by \$50 in 2002
Explanation
The statement "the tuition increased by \$50 in 2002" is not correct because according to the graph, the tuition remained the same from 2001 to 2002, indicating no increase.
