Question 1

When viewing tabulated research results,readers or listeners need exact statistics rather than rounded fractions and percentages.

Accepted Answer

Rounded fractions and percentages are often used in tabulated research results to simplify the information and make it more accessible to readers or listeners, without significantly impacting the understanding of the data.

Question 2

A graphic that will not fit on the page where it is introduced should be placed in an appendix.

Accepted Answer

False

Question 3

Graphics in reports generally do not need titles because their content is obvious.

Accepted Answer

While the content of graphics may seem obvious, including a title can provide context and clarity for the reader. It also allows the reader to quickly identify what the graphic is representing without having to analyze it in detail.

Question 4

Fractions,percentages,and the Dow Jones industrial averages are examples of the common language used in communicating difficult or complex numbers.

Accepted Answer

Fractions, percentages, and the Dow Jones industrial average are all examples of commonly used numerical concepts that aid in expressing complex or difficult numbers.

Question 5

Graphics should clarify,simplify,or reinforce the text discussion.

Accepted Answer

Graphics are designed to support and enhance the text discussion by improving comprehension, reducing complexity, and adding visual appeal.

Question 6

A pie chart is the best type of graphic aid to use to summarize the results of a survey question to which each respondent could check more than one answer.

Accepted Answer

A pie chart is best for showing the parts of a whole at one point in time and cannot accurately represent responses where participants can choose more than one option, as the total can exceed 100%. A bar chart or a stacked bar chart would be more appropriate for such data.

Question 7

The extreme use of color,complicated symbols and art techniques,and unusual combinations of typefaces,should be avoided because they can distract and bury relevant data.

Accepted Answer

The extreme use of color, complicated symbols and art techniques, and unusual combinations of typefaces can indeed distract and bury relevant data, so it is usually best to avoid them in order to ensure clear and effective communication.

Question 8

People who want to understand the interpretation of data are generally more interested in reading about proportions and ratios than about specific numbers.

Accepted Answer

Proportions and ratios provide a sense of relative magnitude and context, which is often more meaningful than specific numbers. This helps people understand the data in a more practical way.

Question 9

To depict sales trends for the past five years,you would create a bar chart with the y-axis beginning at the lowest value reported.

Accepted Answer

To depict sales trends over time, a line chart is more appropriate, and the y-axis should ideally start at zero to accurately represent the data's scale and variations.

Question 10

When report writers present quantitative data,it is their ethical responsibility to provide all of the data rather than just a graphic representation of the data.

Accepted Answer

While it is important to present data accurately and ethically, providing all of the raw data is not always necessary or practical, especially in summary reports or presentations. The key is to ensure that the graphic representation accurately reflects the data and does not mislead the audience.

Question 11

"Talking titles" that interpret the data shown in a graphic are recommended in reports rather than general headings such as "Results" or "Findings."

Accepted Answer

Talking titles help to provide a clear and concise interpretation of the data presented in a graphic, making it easier for the reader to understand the key findings of the report. General headings such as "Results" or "Findings" are too broad and do not provide enough specific information. Therefore, it is recommended to use talking titles in reports to effectively communicate the data presented.

Question 12

For Kayla to avoid a visual distortion in the bar chart she is creating to show her company's sales by region,she should design the quantitative axis to begin at zero,and make each bar the same width.

Accepted Answer

Starting the quantitative axis at zero and making each bar the same width ensures that the differences between the values are accurately represented without exaggeration or distortion.

Question 13

Data that can be presented in a pie chart may also be presented in a bar chart,but the reverse is not always true.

Accepted Answer

This is because a pie chart shows fractions or percentages of a whole, while a bar chart shows numerical values or quantities. It is possible to convert data from a pie chart to a bar chart, but some information may be lost in the process.

Question 14

A pictogram could be used to track progress toward completion of a six-month construction project.

Accepted Answer

The answer of A pictogram could be used to track...

Question 15

Labeling each piece of a pie chart is not required,as long as the most important pieces are explained.

Accepted Answer

Labeling each piece of a pie chart is important to avoid confusion and to provide accurate information about the data.

Question 16

Flip charts and white boards are obsolete and have been replaced by electronic presentations.

Accepted Answer

While electronic presentations are more commonly used now, flip charts and white boards are still used in many settings, particularly in small group or interactive sessions. They also offer a tangible, visible way to collaborate and brainstorm ideas.

Question 17

While text can be given an unethical slant,graphic aids eliminate that risk because of their quantitative nature.

Accepted Answer

Graphic aids, just like text, can be presented in an unethical or misleading manner. The way the data is represented, the choice of scale, and the design elements used can all contribute to an unethical or biased presentation of information. Therefore, it is important to critically evaluate both textual and graphical information.

Question 18

Data on the growth of online business transactions over a five-year period would best be shown in a line chart.

Accepted Answer

Line charts are best suited for tracking progress and changes over time, making them an ideal choice for displaying data on the growth of online business transactions over a five-year period.

Question 19

A line chart is an effective graphic for comparing housing prices in a particular state or region with housing prices in the United States over a five-year period.

Accepted Answer

A line chart can show trends and changes in data over time, making it a useful tool for comparing housing prices in a particular state or region with the national average over a period of five years.

Question 20

You want to show total U.S.auto sales in each year since 2005; the data could be illustrated using either a pictogram or a bar chart.

Accepted Answer

Both pictograms and bar charts can be used to show changes in data over time, but for this specific question, a bar chart would be the more appropriate choice to show the total sales in each year since 2005. A pictogram may be more useful when comparing values for different categories, such as sales of different brands of cars or different types of vehicles.
