All we know about the world teaches us that the effects of A and B are always different-in some decimal place-for any A and B. Thus asking “are the effects different?” is foolish.
The greatest value of a picture is when it forces us to notice what we never expected to see.
An approximate answer to the right problem is worth a good deal more than an exact answer to an approximate problem.
The best thing about being a statistician is that you get to play in everyone’s backyard.
The combination of some data and an aching desire for an answer does not ensure that a reasonable answer can be extracted from a given body of data.
There is no data that can be displayed in a pie chart that cannot be displayed better in some other type of chart.
This is my favorite part about analytics: Taking boring flat data and bringing it to life through visualization.
It’s better to solve the right problem approximately than to solve the wrong problem exactly.
When communicating results to non-technical types there is nothing better than a clear visualization to make your point.
Visualization is often used for evil – twisting insignificant data changes and making them look meaningful. Don’t do that crap if you want to be my friend. Present results clearly and honestly. If something isn’t working – those reviewing results need to know.
Numerical quantities focus on expected values, graphical summaries on unexpected values.
In a world in which the price of calculation continues to decrease rapidly, but the price of theorem proving continues to hold steady or increase, elementary economics indicates that we ought to spend a larger and larger fraction of our time on calculation.
Be approximately right rather than exactly wrong.
Far better an approximate answer to the right question, which is often vague, than the exact answer to the wrong question, which can always be made precise.
In a single sentence the moral is: admit that complexity always increases, first from the model you fit to the data, thence to the model you use to think about and plan about the experiment and its analysis, and thence to the true situation.
I know of no person or group that is taking nearly adequate advantage of the graphical potentialities of the computer.
If a thing is not worth doing, it is not worth doing well.
