Presenting numbers in slide format can be a challenge. Unless you are some form of mathematicaphile (I think that’s a made-up word) you probably don’t get much of a charge at looking at slides full of numbers.
Another drawback to filling a slide with data is that your audience is no longer paying attention to you; they are busy reading all the not-so-interesting bits of data on the slide.
Your audience didn’t come to see your slides, they cam to hear your interpretation of the slides. If you just want them to read the slides, you can just email them a copy of your slideshow and cancel the meeting.
Let’s look at an example.
Not only is your audience reading the data (and not listening to you) but they are trying to make sense of the data. This is a roll of the mental dice because they may come to a different, possible incorrect conclusion as opposed to your intent.
Suppose we presented the same data in the following manner.
From just the title of the slide, your audience is made aware of the most critical point about the data.
The supporting chart makes it easier to understand the performance hierarchy due to the color coding and sorted order of the chart.
The important facet of this design is that you guide the viewer’s eyes to the most important topic.
Notice the obvious interpretive difference between the next two slides.
