Question 1

Using too many charts will dilute the value of the really important ones.

Accepted Answer

Including too many charts may overwhelm readers and make it difficult for them to identify which ones are the most important. Hence, it is essential to use charts sparingly and strategically to ensure that they add value to the content.

Question 2

The bar chart serves in some ways as a dynamic pie chart.

Accepted Answer

A bar chart displays data in rectangular bars, while a pie chart shows data as different segments of a circle. While both types of charts convey information about proportions or percentages, they present the data in different ways. Therefore, a bar chart does not serve as a dynamic pie chart.

Question 3

Which of the following pairs of charts are used for similar purposes?

Accepted Answer

All of these pairs of charts are used for similar purposes. Pie charts and one-scale bar charts are both used to show proportions of a whole. Line charts and two-scale bar charts are both used to show trends over time. Stratum charts and divided bar charts are both used to show the distribution of data within a category.

Question 4

An analyst wishes to combine the information illustrated by six annual pie charts of market share for four categories of automobile manufacturers.Which of the following is the most appropriate chart for this purpose?

Accepted Answer

The answer of An analyst wishes to combine the information...

Question 5

Pie charts are useful for illustrating trend relationships.

Accepted Answer

Pie charts are useful for illustrating proportional relationships among categories, but they do not show trends over time. Line graphs or bar charts are more appropriate for illustrating trend relationships.

Question 6

A stratum chart is equivalent to a line chart.

Accepted Answer

A stratum chart represents data in distinct groups or layers, while a line chart represents data points connected by line segments. They are not equivalent.

Question 7

An analyst wishes to emphasize the magnitude (in dollars)of sales generated by each of three brands for the year ending December 31,2012 as well as the relative sales of each brand.Which of the following is the most appropriate chart for this purpose?

Accepted Answer

A one-scale bar chart would be the most appropriate chart for comparing the magnitude and relative sales of each brand. It allows for easy comparison of the sales of each brand, and the use of a single scale makes it clear which brand has the highest sales.

Question 8

The main difference between the two popular forms of organizing an oral report are where the conclusions are introduced.

Accepted Answer

The two popular forms of organizing an oral report are the deductive approach, where the conclusions are introduced at the beginning of the presentation, and the inductive approach, where the conclusions are introduced at the end.

Question 9

In general,it is better to have too little technical detail than too much in an oral report.

Accepted Answer

It is better to keep an oral report concise and understandable for the audience. Too much technical detail can confuse or bore the listeners, and may obscure the main points that need to be conveyed. It is important to strike a balance between technical accuracy and accessibility of information in oral presentations.

Question 10

When the variable you need to present contains more than about five or six levels,which type of graphic or chart should you avoid using to depict it?

Accepted Answer

Pie charts become confusing and difficult to read when there are too many slices, which often occurs with more than five or six levels.

Question 11

The use of graphics (charts)never gets in the way of effective communication.

Accepted Answer

Graphics can enhance communication by simplifying complex information, but if used improperly, they can also confuse or mislead the audience, thus hindering effective communication.

Question 12

When giving the oral presentation,it is recommended to use no more than a quarter of the time for the formal presentation,saving the rest for questions and answers.

Accepted Answer

It is generally recommended to use the majority of the allotted time for the formal presentation, leaving a smaller portion, often the last 10-15 minutes or so, for questions and answers, depending on the total length of the presentation slot.

Question 13

One advantage of the one-scale bar chart over the pie chart is

Accepted Answer

The one-scale bar chart allows for the indication of the magnitude of the variable categories, whereas the pie chart only displays relative percentages. This can be particularly useful when comparing categories that have significantly different values. It is not stated that the one-scale bar chart is easier to understand or illustrates change over time, so options B and D are not correct. Option E is partially correct, but the one-scale bar chart provides more information than just relative percentages. Option A is incorrect because the one-scale bar chart has an advantage over the pie chart.

Question 14

There is no risk of being led to the wrong conclusion when reading pictograms.

Accepted Answer

While pictograms can provide helpful visual information, there is always a possibility of misinterpreting or misunderstanding them. Different cultures or contexts may interpret the same pictogram differently, leading to potential confusion or incorrect conclusions.

Question 15

A chart that uses symbols instead of a bar to indicate length is a variation of a bar chart called a

Accepted Answer

A chart that uses symbols instead of a bar to indicate length is called a pictogram.

Question 16

Graphics should be used only to illustrate key findings and when they allow insights into data that might not be seen otherwise.

Accepted Answer

Graphics can be a powerful tool to aid in the interpretation and understanding of data. However, using graphics unnecessarily or inappropriately can be distracting or misleading. Therefore, it is important to use graphics only when they enhance the understanding of key findings or allow for insights that may be overlooked in tabular form.

Question 17

Which type of bar chart is most useful to illustrate the change in two or more series through time?

Accepted Answer

A grouped-bar chart is the most useful type of bar chart to illustrate the change in two or more series through time because it allows for easy comparison between the different series at each time point. Stacked-bar charts, divided-bar charts, and two-scale bar charts can be confusing to interpret and may not accurately show the changes over time. A one-scale bar chart may be useful for comparing changes within a single series over time, but it does not allow for easy comparison between multiple series.

Question 18

When presenting the oral research report,the conclusions should always be stated after the results have been presented.

Accepted Answer

The answer of When presenting the oral research report,the conclusions...

Question 19

Which of the following is NOT one of the rules for delivering a good oral presentation?

Accepted Answer

While it is important to dress professionally and appropriately for the occasion, there is no set rule that requires formal business attire for a good oral presentation. This can vary depending on the context and audience.

Question 20

Pie charts are effective for depicting relative size.

Accepted Answer

Pie charts are commonly used to show relative sizes or proportions of different categories in a dataset. Each slice of the pie represents a different category and the size of the slice corresponds to the proportion or percentage of the total that category represents. This makes it easy for viewers to quickly compare the relative sizes of each category.
