Technical people delivering technical presentations have an additional burden which non-technical speakers don’t have to worry about – how to represent data on their slides.

Regarding data representation in technical presentation slides, presenters should focus on the following areas:

Accurate and Objective Representation of Data

Ensure that the data presented is accurate and not altered to create a misleading narrative. Represent data truthfully, including potential limitations or uncertainties in the analysis.

You want your data to be foolproof without the chance of being disputed by someone in the audience. You should anticipate questions your audience may have about your data and be ready to respond with previously practiced answers.

Data should always be presented within a clear context to avoid misinterpretation. Include relevant benchmarks, comparison points, or baselines to ensure the audience understands the data’s significance.

Analogies concerning your data can make the data more straightforward for your audience. Ensure you show the context. Data can mean different things in different contexts.

Misleading scaling in graphs or using inconsistent units can distort the interpretation of results. Always label axes and provide units of measurement for clarity.

Ensure your axis labels and units in your graphs are clearly labeled and understandable to your audience.

So, regarding data representation in technical presentation slides, you should focus on accurate and objective representation of your data.

Another focus area should be consistency in visual and content representation.

Consistency in Visual and Content Representation

Use consistent design elements like color schemes, fonts, and formatting. Visual consistency helps the audience stay focused on the content without being distracted by design changes.

Companies brand their messages similarly, so when the visual of their advertising is displayed, there is no question about which company is advertising.

If you use multiple graphs or charts, ensure that similar data types are represented consistently. For example, if showing multiple trend graphs, keep the axes and colors uniform to make comparisons easier.

Do this to remove another distraction from your audience’s mind. You want your audience to focus on your message, not the inconsistent format between graphs or charts.

Prioritize information on slides through effective use of spacing, headings, and font sizes to guide the audience’s attention to the most essential parts.

Also, remove anything, and I mean anything, from the slide if it does not contribute to your presentation message.

So, regarding data representation in technical presentation slides, you should focus on accurate and objective representation of your data and consistency in visual and content representation.

A final focus area regarding data representation in technical presentation slides is inclusivity and accessibility in representation.

Inclusivity and Accessibility in Representation

Consider that some audience members may have color vision deficiencies (e.g., color blindness). Use patterns, labels, or high-contrast color schemes to ensure that your slides are understandable to everyone.

You will never know if any of your audience members have color vision deficiencies, but it is worth your extra effort if you can prevent them from struggling with the colors in your slides.

Sometimes, using a variety of ways to represent the same data (e.g., a chart and a bullet point summary) can help cater to different learning styles and ensure comprehension.

Your audience’s members may have different ways to learn more easily. Bulleted words on your slides may be acceptable for some of your audience. However, there will be other audience members who learn more easily from charts or graphs.

The best way to help each of these audience members with different ways of learning is to mix up your slides with words on some charts and graphs and charts on others. You may also want to put words and charts/graphs on the same slide.

While it’s a technical presentation, remember that representation also means making content accessible. Avoid using excessive jargon, abbreviations, or acronyms without explanation to ensure everyone follows along.

If you must use jargon, abbreviations, or acronyms, you may consider distributing a handout sheet with these defined before your presentation.

So, regarding data representation in technical presentation slides, you should focus on accurate and objective representation of your data, consistency in visual and content representation, and inclusivity and accessibility in representation.

By focusing on these areas of your technical presentation, you can create slides that are accurate, consistent, and accessible to all members of the audience, enhancing both clarity and engagement.

Remember, it’s all about them, not about you. Create, practice, and deliver your technical presentation with only the audience in mind.

If you do this, your presentation will be successful!
