Arguing with Numbers

How to write and talk about data


Data analysts often need to write reports that summarize their findings. And they often have to present their findings to meetings. Arguing with Numbers is a one-day course that teaches the skills needed to write and talk about data effectively. We address short-form narratives in the first half of the course and long-form narratives in the second.


Session 1
09:30 to 11:00
Topping and tailing single data exhibits

The first session of the course teaches the elements of how to introduce and describe a datagraphic in a one-side-of-A4 written document or in a short spoken presentation. We go through several teaching examples and exercises to practice and 'cement' these elements.

How to talk about a datagraphic in two minutes. The dark green boxes at either end of this diagram represent the introduction (H) and summary (G2), each of which will take about 20 seconds, And yes, I know the word 'introduction' doesn't begin with the letter H—and 'summary' doesn't begin with G2 either—but the letters get explained on the course. The black vertical line is the moment when you reveal your datagraphic. The mid-green boxes (D1, D2 and D3) are when you explain the dimensions of the datagraphic, and the pale green boxes are when you tell the audience what you think the chart is saying.

Session 2
11:15 to 12:45
Make your text flow

In the second session we cover the techniques needed to make your text flow. From Glasgow Caledonian University's 'hook-and-eye' approach to David Hume's Enlightenment philosophy, we get participants to see how sentences, paragraphs and datagraphics should connect together. And we steal from Ros Atkins the idea of drafting a 'guide script' in a conversational tone of voice to audit our presentation for 'point-to-point connectivity'.

A paragraph doesn't just consist of a group of sentences all on the same topic. The sentences have to be connected together. An idea in the first sentence has to be picked up by sentence two. And an idea in the second sentence has to be picked up in the third sentence. And so on. Sometimes, the 'idea' is not a word or a phrase but—instead—a datagraphic.

Session 3
13:30 to 15:00
Shape and structure for longer documents and presentations

When your data-rich report is a longer one (several pages), or when your data presentation is going to run to longer than just two minutes, you need to apply different techniques for shaping and structuring your content. In this session we show how to build a data argument from scratch, showing what needs to be included in each section, and how exactly to insert data exhibits into the appropriate points in the argument.

When designing longer data presentations, a useful metaphor to have in mind is the video editing software metaphor. In particular, the action of dragging and dropping audio, video and still images into the timeline so that they synchronize with the narration.

Session 4
15:15 to 16:30
Connecting the sections of an argument

In the final session of the course we work on how best to join up the various sections of our report. How do we decide which of our three points to make first? How do we segue from the first point to the second point without making the audience think we've missed a beat?


Arguing with Numbers can be booked as either an on-site face-to-face course or as a virtual course (via Microsoft Teams) for £1,250+VAT, and up to 12 participants can be accommodated in each workshop session. Email info@kurtosis.co.uk to start making arrangements.
