Example of “telling a story”

Anytime you have data, use visuals to help tell your story. For example, which of these graphs below makes it easier to understand? Both show the majority of the countries will have between 1-3 children. Both show outliers. (Quiz)

Which of these might contribute more to your story? By using an overlay, we see the outliers more clearly and we can even identify the countries that show the outliers!

Example 1 - Simple Scatter plot

Example 2 - Overlay, Children x axis

Table 42:Fertility plotted with majority 1-3 children

Table 43:Fertility shows countries, with overlay to easily spot outliers

However, using an overlay, it is easier to see that we have three outliers in example 2

We can easily see one outlier in example 1
