Could anyone at the talk explain the three charts on slide 62? What are they representing?


Hi,

Those 3 chart types are the only data visualizations I recommend using. I should have left out the pie chart, since I don't use those.

I wasted many years of my life at Compete obsessed about "data visualizations" only to learn that no one except me and my statistical team cared about them. Please don't waste as much time as I did playing with exotic visualizations.

He asked if you could explain them, specifically what they are about I think.


Sorry not sure what you mean.

Do you mean explain what a line, bar & pie chart are good for?


Ohh I am sorry I thought you were emphasising the data the charts were measuring rather than the actual types of chart themselves!

If you only mean that we should use only line, bar or pie charts, then I would say that scatter graphs at time have a good use of showing outliers, such as some guy who spends say ten minutes on the site, or visually able to show for example how many people spend ten minutes and how many 3. Communicate in other words much more information than a line, bar or pie chart can at times. I mean, people did not invent these other charts for no reason :)
