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.
- Center. This arc is part of a circle. Where is its center? The arc was 94° of its circle, 26% of the way round. The shorter the arc, the less it says about its center.
- Average. Where is the average height of these bars? 5 bars, at 30, 22, 81, 100 and 50% of the tallest. Their average is 57%, above the halfway line.
- Mark. Mark 3/5 of the way along the line, starting from the dot. 3/5 is 60% of the way along the line from the dot.
- Share. What percent of the shape is colored? The shape was a teardrop, cut by a straight line: 83% of it colored, 17% not.
- Ratio. By area, the big circle is how many of the small one? The big circle is 2.28 times as wide as the small one, and area goes as the square of the width: 2.28 × 2.28 is 5.2.
