Question

Dante measured the length of several pencils he found in his desk. He used a stem and leaf plot to organize the data. What is the difference between the length of his longest pencil and his shortest pencil? A) 1.2 cmB) 0.3 cmC) 2.6 cmD) 1.4 cm

Answer 1

From the stem and leaf plot, let's write the data set:

10.9 cm

11.0 cm

11.2 cm

11.2 cm

12.1 cm

12.3 cm

We need to find the range of the data set, which is, the difference between the length of the longest pencil and the shortest pencil.

From the data set, we can see:

• Length of Longest Pencil = 12.3 cm

,

• Length of Shortest Pencil = 10.9 cm

The difference is

12.3 - 10.9 = 1.40 cm

Answer1.4 cm
