Summary: This is the eighth episode of the current Crash Course series,
“Navigating Digital Information”. It looks at data and infographics to
show how data can be represented and misrepresented. It is geared to
a high school audience.
Major takeaways:
-data needs to be accurate & relevant
-sources need to be reliable
-data needs to be represented honestly and contextually
Evaluation: I have really been enjoying the new Crash Course “Navigating
Digital Information“ series and this week’s episode seemed especially pertinent
to our class because we will soon be working on visual representations of our
collections. This youtube video discusses how visual representations can be used
to enhance or obscure an information consumer’s understanding of data.
One example is the National Review and the Washington Post using the same
NASA data to represent climate change.

The chart on the left, billed by the National Review as “the only climate change
chart you’ll ever need”,makes it look like the climate hasn’t been warming by
using a y axis of values between -10º-110º. On the Washington Post’s chart’s y
axis goes from 55º-60º. Crash Course also emphasizes that context is important.
For example, if you know that small shifts of even a degree of global temperature
are unusual and can impact climate, the Washington Post’s chart seems more
relevant than the National Review’s although both are technically correct.
As I develop infographics for my collection I will have to make sure to
provide context and guard against misrepresenting my data.
