Excerpt:
Jitter charts are my new favorite tool for displaying how distributions change over time.
I used them to great effect in my recent post One Bad Year? Comparing the Long-Term Public Pension Fund Returns Against Assumptions.
I’m often looking at distributions, and wanting to communicate something about how those distributions change over time, or how distributions compare. Often, I have to simply pick out key percentiles in those distributions, or key aspects, such as mean and standard deviation.
But why not graph all the points in one’s sample directly, if one has them?
That’s where jitter charts can help.
