(90-minute LIVE online class)

A crash course that helps you create impactful and easy-to-understand DATA PRESENTATIONS.

PRESENTING DATA. What is this crash course about?

In the last few months, I’ve seen a lot of data presentations — at conferences, online presentations, company meetings. 90% of these were just awful. Confusing charts, too many details, puzzling screenshots of huge spreadsheets, pointless explanations, etc… 

Presenting data can be an issue even for the most talented public speakers.

It’s not rocket science though! One should just follow ~10-12 key principles, consistently. Yet, most data presentations are ugly and incomprehensible. 

That hurts everyone: the presenter can’t deliver their message — and in the meantime, the audience bore themselves to death.

But that’s an opportunity for you!

To deliver an impactful and impressive presentation, you don’t have to be a Photoshop guru; you don’t have to create artistic diagrams, and you don’t have to become a master of rhetoric. You can be outstanding by following a few basic principles and by avoiding common mistakes. I tell you by experience: simple, clean, and easy-to-understand presentations are rare. And for that, the audience always appreciates when they can see one.

In this 90-minute crash course, I’ll show you the few rules that will help you to deliver successful data presentations 
for the next 10 years!

Who is this crash course for?

For everybody who has to present data.

If you are just starting your journey with data presentations (or if you are doing it for a while but you are not satisfied with yourself), this online class will help you build a solid foundation and avoid common mistakes.

If you are a bit more advanced, then this class will help you organize and structure your already-existing knowledge — and bring to the conscious level the things that you have done well “only” intuitively so far.

The data presentation topic is especially important for: 

More than 2,000 people attended my data science courses and workshops — from companies like:

hey, I’m Tomi Mester, a practicing data analyst, and researcher since 2012. I have worked for Prezi, iZettle (acquired by Paypal), and several small and midsize businesses as an analyst/consultant. I’m the author of the Data36 blog where I teach data science.

I have to present data a lot. It’s my passion, too: I’ve taught it at the university and I’ve held presentation workshops for big companies, too. I’ve presented at conferences like TEDx (in front of 500 people), PechaKucha Night (300 people), Barcelona E-commerce Summit, Stockholm Analytics Day, etc.
