We watched a fascinating YouTube video for a Hans Rosling
TEDTalk this week. I don’t know how Dr.
Rosling was able to animate his analysis on the slides he had in the video, but
the insight is so much more powerful watching motion convey the differences
over time. Time series data graphed as
multiple lines on a chart are very helpful, but watching motion is so intuitive
for seeing the magnitude and speed with which values are changing. I remember my first Kelley Connect week,
where some tools for data visualization were presented that blew my mind. I had never really seen a bubble chart
before, where 3 variables can be represented in 2D space by having the bubble
size correspond to a third variable. Another
example occurred this week as we were presented a collage of our wiki responses
from the first week of the definition of marketing. More common ideas showed up in the collage as
larger words to convey their relative frequency. These ideas are causing me to be less and
less patient with the traditional way of presenting data, where teams believe
that an overwhelming number of line and bar charts in a PowerPoint deck will
get the point across. I think the goal
is for anyone in your target audience to be able to instantly grasp the
information that’s conveyed visually.
The overall insight Dr. Rosling found was that the ‘we’ and ‘them’
characterization of the world is rapidly changing. It’s not just developed vs. Third World
anymore. Even developing countries are
seeing families shrink and live longer, looking more and more like developed
countries. Family planning was cited as
a key driver. Dr. Rosling points out
that we need to look at the data rather than just make assumptions that lead to
myths. He also pointed out that even
regional perceptions can be wrong, because there are huge differences among the
data within Arab states, Africa,
Eastern Europe, or Asia. For instance,
he discussed the strong correlation between GDP/Capita and Child survival
percentage, but within a given region there are huge differences depending
usually upon governmental attitudes towards trade, etc. We just need to be cautious of the averages
we use and the context in which we use them.
What’s amazing is that he was using publicly funded data and
advocating strongly that we improve the ability to search these free
databases. A lot of insights can come
from it. It certainly shattered my
impression of the Third World being a place where life expectancy dramatically
trailed the West because of income disparities.
Dr. Rosling may not have been using these data for market research for a
product, but the big takeaway was seeing how real data will provide the
insights to make good, informed decisions.
