1. John Tukey

John Tukey (American mathematician and statistician)

Tukey invented many terms such as "bit" (for binary digit), ANOVA (Analysis of Variance), etc. He is responsible for the following.

FFT (Fast Fourier Transform) algorithm
Box plot and stem and leaf diagram

2. Bit as binary digit

John Tukey (American mathematician and statistician) , working with John von Neumann, coined the term "bit" as "binary digit". The classical "bit" has one of two values, which can be represented as 0 (usually taken as false) and 1 (usually taken as true).

The term "bit" was first used in an article by Claude Shannon in 1948.

3. Approximate answers

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. John Tukey (American mathematician and statistician)

4. Approximate answers

An approximate answer to the right problem is worth a good deal more than an exact answer to an approximate problem. John Tukey (American mathematician and statistician)

5. Problem solutions

It's better to solve the right problem approximately than to solve the wrong problem exactly. John Tukey (American mathematician and statistician)

6. Right

Be approximately right rather than exactly wrong. John Tukey (American mathematician and statistician)
