Exploring Stem-and-Leaf Plots

The video tutorial introduces stem-and-leaf plots as a method to display data, highlighting their advantage of showing original data values. It explains how to create a stem-and-leaf plot by splitting data into leading and trailing digits and organizing them into a t-chart. An example is provided using numbers from 10 to 45, demonstrating how to categorize stems and leaves. The tutorial emphasizes the importance of including a key to clarify the representation of data points.

What is a primary advantage of using stem-and-leaf plots over other types of data displays?

• They allow for better data manipulation.

• They are easier to create.

• They show the original data values.

• They require less space.

What are the two parts into which data is split in a stem-and-leaf plot?

• Stems and leaves

• Stems and branches

• Roots and leaves

• Digits and numbers

In a stem-and-leaf plot, what does the stem typically represent?

• The lowest value of data

• The highest value of data

• The leading digits of the numbers

• The trailing digits of the numbers

What does the leaf in a stem-and-leaf plot represent?

• The leading digits of the numbers

• The trailing digits of the numbers

• The total count of data points

• The average value of the data

If a dataset includes the numbers 22, 22, and 24, how are these represented in the leaves?

• As 4, 4, and 4

• As 2, 2, and 2

• As 2, 2, and 4

• As 22, 22, and 24

How are repeated data points shown in the leaves of a stem-and-leaf plot?

• By increasing the stem value

• By listing the leaf multiple times

• By underlining the repeated leaves

• By placing a special symbol next to the leaf

What is the purpose of a key in a stem-and-leaf plot?

• To identify the highest data point

• To explain how to read the plot

• To provide a title for the plot

• To list all the data points

In the context of the provided data, what does a stem of '1' and a leaf of '0' represent?

• 1.0

• 10

• 0.1

• 100
