Using statistical charts to analyze data and turn data
In pictures, people can read the original data faster through visual symbols.
Comparing charts present the statistical charts to improve people's
understanding of data.
One of the most important conclusions I've learned in two
chapters is that any chart, no matter how well designed, can mislead us if we
don't pay attention. If we want to read the graph well, we have to pay
attention to the nature of the content of the chart. In a nutshell, a figure is
a way of turning symbols into language.
The core element of most charts is its visual coding. My
favorite graph is bar graph. The reason is that most people know the bar graph
and can understand what it means. The bar graph is very straightforward and
gives us accurate information — the number of different lengths used in the bar
statistics. Then the bar in a particular order. It's easy to see how many there
are in the bar chart, so I think kids can understand that.
