by placing the hand on the edge of a piece of paper and marking the tips of the thumb and little finger, the student can measure a straight line. this is a better method than placing the hand directly on the ruler.

what is the largest hand span? ____ cm
what is the smallest hand span? ____ cm
what was the most common hand span length? ____ cm

Explanation:

Part 1: Largest Hand Span

Step1: Analyze the dot plot's x - axis (length in cm) and find the rightmost dot.

Looking at the x - axis labels (10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25) and the dots, the rightmost dot is at 23 cm.

Step1: Analyze the dot plot's x - axis and find the leftmost dot.

Looking at the x - axis labels and the dots, the leftmost dot is at 14 cm (since there are no dots at 10, 11, 12, 13).

Step1: Count the number of dots for each length.

For length 16 cm: Let's count the dots. By looking at the plot, the number of dots at 16 cm (we can see the vertical stack) - from the y - axis (number of students), we can see that the length with the most dots (highest frequency) is 16 cm (by counting the dots, the stack at 16 cm is the tallest).

Answer:

23
