Chapter 2: Q.2 (page 125)

The height in feet of 25 trees is shown below (lowest to highest). 25,27,33,34,34,34,35,37,37,38,39,39,39,40,41,45,46,47,49,50,50,53,53,54,54

Short Answer

Expert verified

In the stem plot it is noticed that most of trees have their height concentrated around 30feet. There is no outliner for the given data.

Step by step solution

01

Step 1:Content Introduction

A stem and leaf plot divides data into stems (the greatest digit) and leaves (the lowest digit) (the smallest digits). Stem-and-leaf diagrams are excellent for illustrating the relative density and form of data, providing a fast summary of the distribution to the reader. They keep (most) of the raw numerical data, which is typically in great condition. They can also be used to find the mode and identify outliers.

02

Content Explanation

The steps to create step plot are written below:

  1. Divide each observation of data into stems and leaf.
  2. Write stems in vertical line from smallest to largest.
  3. Draw a vertical line to the right of the stems
  4. Write leaves in increasing order next to their corresponding stem.
03

Conclusion

For the given data stem plot is constructed,

From the above stem plot it is noticed that most of trees have their height concentrated around30 feet. There is no outliner for the given data.
