Round by round
A round scores 100 for a guess within a small margin of the truth and falls in a straight line to 0 for a wild one; the day is the average of the five. The pictures are the game — these are the figures behind them.
- Ratio. By area, the big circle is how many of the small one? The big circle is 3.16 times as wide as the small one, and area goes as the square of the width: 3.16 × 3.16 is 10.0.
- Angle. Make a 77° angle. The angle to make was 77°, 13° short of a right angle.
- Path. The squiggle is how many bars long? The squiggle bends 5 times. End to end in a straight line it spans 1.7 bars; along the curve it is 6.5.
- Average. Where is the average height of these bars? 8 bars, at 100, 71, 77, 98, 97, 32, 45 and 88% of the tallest. Their average is 76%, above the halfway line.
- Share. What percent of the shape is colored? The shape was a plus, cut by a straight line: 21% of it colored, 79% not.
