Presentation Skills Training Effective Visual Aid Design 2 — Questions and Answers
Question 1: What is the recommended maximum number of bullet points per slide to maintain audience focus?
- 3-5 bullet points (Correct answer)
- 8-10 bullet points
- 6-8 bullet points
- 10-12 bullet points
Correct answer: 3-5 bullet points
Limiting slides to 3-5 bullet points prevents cognitive overload and keeps the audience focused on key ideas.
Question 2: Which chart type is BEST suited for showing how individual parts contribute to a whole?
- Pie chart (Correct answer)
- Line graph
- Scatter plot
- Bar chart
Correct answer: Pie chart
Pie charts are ideal for displaying part-to-whole relationships when you have a limited number of categories.
Question 3: When using color in visual aids, what is the primary accessibility concern to address?
- Color blindness among audience members (Correct answer)
- Personal color preferences
- Printer ink costs
- Screen brightness levels
Correct answer: Color blindness among audience members
Approximately 8% of men have color blindness, so designers must ensure information is conveyed through more than color alone.
Question 4: What does the term 'signal-to-noise ratio' mean in the context of visual aid design?
- The ratio of meaningful content to distracting elements (Correct answer)
- The audio volume relative to background noise
- The contrast between text and background
- The number of slides versus speaking time
Correct answer: The ratio of meaningful content to distracting elements
A high signal-to-noise ratio means the visual contains more useful information and fewer decorative or irrelevant elements.
Question 5: Which font size is generally considered the minimum for body text in projected presentations?
- 24pt (Correct answer)
- 10pt
- 14pt
- 18pt
Correct answer: 24pt
24pt is the commonly recommended minimum for body text to ensure readability from the back of a typical presentation room.
Question 6: What is 'chartjunk' in presentation design?
- Unnecessary visual elements that clutter charts without adding information (Correct answer)
- Outdated or inaccurate data in charts
- Charts that are too small to read
- Using too many different chart types in one presentation
Correct answer: Unnecessary visual elements that clutter charts without adding information
Edward Tufte coined 'chartjunk' to describe decorative elements like 3D effects, gridlines, and clipart that add visual complexity without aiding comprehension.
Question 7: When creating a data table for a slide, what is the best practice for the number of rows and columns?
- Keep it small — ideally under 5 rows and 5 columns (Correct answer)
- Include all available data for completeness
- Use as many rows as needed but limit columns to 3
- Tables should never be used in presentations
Correct answer: Keep it small — ideally under 5 rows and 5 columns
Large tables overwhelm audiences; a small, focused table with the most relevant data is far more effective in a presentation setting.
