If you are familiar with data visualization and presentation of data analysis results, then you’d know the significance of neatly organized findings. You can either show each step of your work with a PowerPoint (PPT) presentation or, if you believe in simplicity and love shortcuts, a project poster is a perfect solution.

The reason why many people prefer posters is that they show you the big picture without delving much into details. Also, posters save time - for both reader and presenter. They highlight only the key points of the project, which comes in handy with complex and long ones. Lastly, we all know how boring a long PPT can be with those endless slides. So boring that we often lose interest and drift away from the actual project. A poster keeps the focus on one page only where you don’t have much space to stray.

Wondering how to design your poster? In this article, I’ll help you get started. I’ll cover the following topics:

What is a Data Science Project Poster and What Makes a Good One?

A poster, usually fitting a single page, is used to present the conclusions you’ve come to during the analysis of your data. It needs to be organized and easy to understand. This means taking care of the little details, such as the font size and colors, so the words are readable and easy to comprehend.

So, how to make a poster which works and also stands out?

  • Words should be readable from a reasonable distance
  • Bullet points, numbering and underlining important concepts do a great deal of organization
  • Different sections should be separated with lines to build a structure
  • The colours should be suitable, neither too bright nor dark, taking into consideration the contrast between the background and the font colour
  • The title should be concise and descriptive

What are the Key Components of a Poster?

A project poster consists of 6 main sections. Each one has its specific purpose and includes the most important elements of your project. To make it easier, I have visualized these sections in the graphic below. Then, I’ll go into detail with each one of them.

Project Title

First, remember to write the name of your project in a large font. Then, add the names of your team members. If you have worked on the project by yourself, it is still a good idea to add your name under the title. After all, you should give yourself some credit for a job well done. Stick to smaller font for the names.

Introduction

Here, you can talk about the problem statement or the idea of your project. The introduction can be a couple of sentences or bullets describing the project’s aim and what your objectives for solving the problem are. You can also include the data source and what inspired you to do the project. For example:

“As stated by the World Health Organization (WHO), stroke is the 2nd leading cause of death globally, being responsible for nearly 11% of total deaths. The main objective of this project is to predict a stroke based on some demographic and clinical features.”

Or another might be: “Kerala is a state in South India where floods affect the whole region due to high rainfall during the monsoon season. In this project, we’ll build a binary logistic model to predict floods based on the monthly rainfall index for each year in Kerala, India.”

Methods

In this part, you explain the steps you’ve taken to achieve the project’s objectives. They can vary from one project to another but let’s say that you’re trying to predict an output using some variables in your dataset by building a predictive model. The basic steps in this case would be:

I- Assessing the data

II- Cleaning the data

III- Training and building the model

IV- Evaluating the model’s performance

Remember to keep it short and to the point. You don't need to mention all the details in each step. Just a summary would be sufficient for the readers.

Results

Now that you’ve elaborated on the methods you've used, in the results part, you have the chance to share the outcomes of your project. This can be as a summary, a table, or a graphic visual to present your findings. Getting back to the example from the methods section where a predictive model was built, the results can be in the following form:

I- Mention the methods used to evaluate the model’s performance

II- Insert an image showing the performance report or a ROC curve

Remember that you don’t have to include all the results because there might be many. Just focus on the points related to the objectives you’ve mentioned in the problem statement.

Visuals & Conclusions

This is your chance to show your artistic side and your deductive skills. There are many cases when people approach the problem correctly and follow the right steps to solving it but, eventually, cannot communicate their findings. This might happen when they lack the ability to draw conclusions that prove the success of their work. It’s just like a detective working on a hard case, eventually able to crack it but then doesn’t show up in court!

There isn’t a specific blueprint when delivering your results. However, here in this section, you can insert some visuals explaining the correlation between different variables and your conclusions based on these correlations. Besides visuals, you can summarize your findings n bullet points to enhance the readability. Or, include bar charts, pie charts, graphs etc. depending on your needs. Let’s go back to the example with the stroke-rate prediction.

Normally, bar charts are useful when comparing data values across certain categories in the dataset. When predicting strokes, a bar chart can depict how many people had or hadn’t had a stroke in each age category.

In the same project, a box plot will show the effect of clinical features, like average glucose level and body mass index, on the likelihood of having a stroke. Also, pie charts are good providing an overview of a certain variable, such as the proportion of males and females in a dataset. Line charts, on the other hand, are best for illustrating a change in a certain variable over time, such as the number of COVID-19 deaths in a year.

All these types of visuals can be used in our example to display different aspects of the findings. Of course, don’t limit your creativity and restrain yourself only to the above-mentioned.

References

Finally, you’ve reached the easiest part of your project poster. In the references section, you need to list the sources you've used or, in some cases, give credit to the people whose work helped you complete the project. This can be:

  • Research papers
  • Authors
  • Articles
  • Books

Final Advice on the Project Poster Structure

There are no specific guidelines or criteria when it comes to designing your poster. The layout can be horizontal or vertical. The number and structure of columns can vary from one to another. Some posters have images, and some don’t. It’s totally flexible. The most important thing is that you deliver your message clearly and organized. Make sure that the language is simple yet descriptive and don’t repeat the same idea over and over. After all, you have limited space so put everything in a structured way.

Examples and Resources

The components I have mentioned so far are the most common structural elements of a project poster. And since we need to see how it all comes together in practice, let’s look at some examples and resources to download free templates for your next data science project!

Example No.1 - Multimodal Neural Decoding with Natural Data

example poster number 1

This one is quite exciting - although the project isn’t simple, it’s presented in a fashionable and organized way, making it easy to understand. As you can see, it has most of the parts I have talked about. The introduction, methods, results, and conclusion, plus enough clear and creative visuals.

Example No.2 - Probabilistic Cause-of-death Assignment Using Verbal Autopsies

example poster number 2

This collaborative project of the University of Washington is discussing how deaths are assigned causes, especially using Verbal Autopsy. This is one way to determine the cause of death using all the available information from recent symptoms to surrounding circumstances. Well, we’d steer away from reading about this project before bed!

Example No.3 - Predicting Discontinuation of Docetaxel Treatment for mCRPC with Hill-climbing and Random Forest.

example poster number 3

After analysing patients’ data in AstraZeneca clinical trial, these guys tried building a model to predict which patients are more likely to discontinue their treatment within 3 months. The poster is quite creative in terms of design, and colour choice, and is structurally pleasing to the eye. Again, the major elements discussed in this article are present.

Example No.4 - Predicting Strokes

example poster number 4

The project’s primary aim is to predict a stroke based on some demographic and clinical features. The project was hosted as a competition on Kaggle a year ago. There are different approaches to solving the problem, but in this poster, a binary logistic regression model was trained to predict the likelihood of a stroke based on the 2 most related features: age & average glucose level.

Resources

If you’d like more details on how to make a poster and get to the very nitty-gritty, I have created a list with useful resources. They vary from explanatory articles to actual guides and templates.

Here is an article by Michael G. Lemieux that explains what a scientific poster is and what to include along with easy tips for designing a good one. Although the article is dedicated to scientific posters for conferences, the basic elements are applicable to any type.

This is a short guide by the NYU libraries that illustrates how to create a research poster. It also starts by defining a research poster and then proceeds with the criteria of a good poster. Beneficial in this article are the examples of both well-designed and poorly made posters. Here you can also find links to software where you can start your design process.

Moving on to the templates, we have the Scientific Poster PowerPoint Templates by MakeSigns. All are free to download!

Also, you can get free-download Microsoft Word templates for research posters by TemplateLab.

This one would be quite useful. Science project poster template by Microsoft which is commonly used specifically for data science projects.

Q&A

Which is the best data visualization tool for a data science project poster?
There are many to choose from. You can use Datawrapper to create 19 different charts as well as data tables and interactive maps. An easy-to-use tool is Flourish Studio. It offers a wide variety of charts and visualization reports, or you can use Tableau Public if you already know how to use it. A more advanced option would be Google Charts if you’re familiar with coding in HTML. The data you’re working on will determine what types of charts you need to create. If, for example, you want to plot a bar chart, then all the above options will work. Yet another great tool that offers plenty of options but is still on the advanced level, is Flourish studio.
How to choose a colour scheme for your data science project poster?
The easiest way would be to check ready-made templates and edit them or construct your own poster and adopt the colour scheme from a template. It’s better to avoid very bright colours since they distract the reader’s attention and the contrast between the font’s colour and the background’s colour may be poor. A rule of thumb is the words are in a dark colour if the background is white or any other light colour, and vice versa.
What is the fastest way to create a poster for a data science project?
Start with a ready-made template for other data science projects! As easy as it sounds, this is the best way to be sure that you’re following the right steps. So, it’s merely adding your results while adjusting the size and colour of some elements in your poster to match the criteria mentioned above. If you like to follow certain steps to get things done, then follow the following steps: 1- Try to gather all the important files from your project in one folder. 2- Create a word document and list the key components of a poster and get the information related to each section from the folder you created. 3- Proofread the document with tools like Grammarly and Quillbot to correct any grammatical mistakes. 4- Choose a suitable template from the resources in this article and download it in whatever format you can edit. 5- Now copy the sections in the word document and paste them to their corresponding place in the template. 6- Finally, take an overall look at the poster and see if you can make any modifications.
