For this discussion, begin by reviewing the techniques of effect sizes and confidence intervals in your textbook. Then, keeping these techniques in mind, read the following quotes:
- “Statistics are no substitute for judgment.”—Henry Clay
- “To not look at the data is foolish, but to look at the data as having all the answers is even more foolish. It is a collision of new-school statistics and statisticians against old-school managers, coaches, and instructors. Neither side is right, neither is wrong; there is so much to be gained from listening to both sides.”—Tim Kurkjian, I’m Fascinated by Sacrifice Flies: Inside the Game We All Love (2016)
- “It ain’t what you don’t know that gets you into trouble. It’s what you know for sure that just ain’t so.”—Mark Twain
- “Good statistical inference never strays very far from the data.”—Brian S. Yandell (2007)
- “An approximate answer to the right problem is worth a good deal more than an exact answer to an approximate problem.”—John Tukey
