Читать книгу Statistical Analysis with Excel For Dummies - Joseph Schmuller - Страница 46

The late, great social commentator, raconteur, and former baseball player Yogi Berra once went to a restaurant and ordered a whole pizza.

“How many slices should I cut,” asked the waitress, “four or eight?”

“Better make it four,” said Yogi. “I'm not hungry enough to eat eight.”

Yogi’s insightful analysis leads to a useful guideline about pie charts: They’re more digestible if they have fewer slices. If you cut a pie chart too fine, you’re likely to leave your audience with information overload.

When you create a chart for a presentation (as in PowerPoint), include the data labels. They often clarify important points and trends for your audience.

(That Yogi anecdote appears in the previous four editions of this book. Did it really happen? We can’t be sure. As Mr. Berra once famously said: “Half the lies they tell about me aren’t true.”)
