Top tips for presenting your data according to research

What do we really know about how to present complex data in ways that are easy to understand and have impacts that might help address complex issues such as climate change? Dr Lucy Richardson explores some of the useful tips provided by data visualisation and communication research that can help you effectively communicate complex information.

This article is part of the ISC’s Transform21 series, which features resources from our network of scientists and change-makers to help inform the urgent transformations needed to achieve climate and biodiversity goals.

Over the last year or so, many people across the world have become used to seeing charts and graphs with COVID-19 statistics in their news feeds, but all charts are not created equal when it comes to effectively communicating a key message.

Researchers have been examining how different aspects of data presentation influence audiences for many years. They have looked at the issue from diverse angles such as which components are viewed in what order and why, and whether text, graphs or maps are more engaging and easily understood. These diverse research questions have been addressed using a wide variety of methods ranging from tracking audience eye movements to surveys and social media polls. From this collection of research, we have gained valuable insights that can help make data visuals more effective communication tools.

A useful framework to think about when designing data visualisations follows the broad process of audience interaction with the presented information: (a) first the audience perceives the information (b) then they think about the information, and (c) then some sort of change or impact occurs due to those thoughts.

Perceiving the information (Perception)

Assuming that your data visualisation is presented to your target audience in a time and place where they are likely to see it, your audience needs to be able to perceive and differentiate each of the key components of your visualisation in order to discern its meaning.

Perception tends to happen in sequence, following a visual hierarchy of attention based on the following characteristics of any object (including maps and graphs): size, colour, contrast, alignment, repetition, proximity, whitespace, and texture and styles. Within each of these elements are further sub-hierarchies. For example, people tend to notice large elements before smaller ones, and bright colours before muted ones. Similarly, dramatic contrasting components are noticed more than those with less contrast.

The effect of these hierarchical elements can be impacted by perception challenges and should be carefully considered to ensure that they promote your message rather than confusing or distracting your audience. There are a range of different perception challenges that can impact on the effectiveness of data visualisations, but did you know there are actually seven different forms of colour blindness? You can even run your data visualisation through a colour blindness simulator to see how it might be viewed by someone with these challenges.

Thinking about the information (Cognition)

When your audience thinks about and derives meaning from information they perceive, this is known as cognitive processing. It includes thinking, knowing, remembering, judging, and problem-solving; any number of which may be used when processing information associated with visualised data.

Some things you can do to help encourage the desired interpretation of meaning from your data visualisation include providing chart titles that are the main message rather than just a description of the content. A title such as ‘Higher amounts of green vegetation in cities is associated with lower summer temperatures’ is much more effective at guiding meaning-making than titling the same chart as ‘Green vegetation and temperature in Australian cities’.

Some topic areas that may require data visualisations can also have underlying psycho-social (psychological, social and/or political) factors that should be considered. This is particularly the case for climate change, a heavily politicised issue that is quite polarising in some countries. When presenting data relating to climate change, some valuable tips include:

  • Avoid catastrophic messaging that can cause people to shut down as a coping response to their fear.
  • Include solutions-based information can help counteract fear by promoting a sense that climate change can be addressed.
  • Provide locally relevant information where possible, as this will resonate more strongly. People are naturally most interested in what happens in their local area.
  • Where possible, consider if there are other ways to cover the issue without mentioning ‘climate change’ if communicating to audiences who may not accept current scientific evidence of its existence and urgency. This is easier for messages relating to adapting to changes in climate than mitigation, as there are often diverse benefits beyond climate change that can be used to frame adaptation information.

It’s also important to recognize that people are generally more likely to remember meaning than detail. This means that people are more likely to remember a trend—such as it’s getting ‘worse’ or ‘better’, ‘increasing’ or ‘decreasing’—but may not remember the specific amount or rate of that increase or decrease.

Changes effected (Impact)

There are a range of possible impacts that might arise from audiences viewing your data visualisation. These could be changes in thought (for example, awareness, understanding, attitudes or concern), or changes in behaviour (for example, information seeking, discussion with others, or even adoption of climate-friendly behaviours). The likelihood of change being effected due to your data visualisation will be enhanced by ensuring your messages are clear and relevant, where clarity will come from effectively addressing perception and cognition considerations and relevance will come from appropriate message framing and consideration of psycho-social factors. Knowing the kind of change you want to achieve will be critical in determining how best to integrate these various factors into your work.

Alternative formats

While most people wishing to present complex scientific data tend to think of charts, graphs, maps, and infographics, it is also possible to present information for perception by other senses such as through sound. Some researchers have been testing data sonification as an alternative to visual data representation. Sonification takes each data point and applies a mix of sound elements that can allow trends to be distinguished—for example, pitch, volume, and choice of instrument—to provide an audio representation of the information. NASA has done this so that people can ‘listen’ to the Milky Way Galaxy, and researchers at the Monash University Climate Change Communication Research Hub have sonified cyclone Debbie’s movements around Australia in 2017.

A free best practice guide has been developed based on a review of data visualisation research. Hopefully, it will help you decide how you can best present your data for effective perception, cognition and impact.
