Stem and Leaf Plot Concepts

In this video, Mr. J introduces stem and leaf plots, a method for organizing and displaying data. He demonstrates how to create these plots using two examples: one with two-digit numbers and another with three-digit numbers. The process involves ordering data, splitting values into stems and leaves, and creating a key for interpretation. The video aims to provide a clear understanding of how to construct and read stem and leaf plots.

What is the primary purpose of a stem and leaf plot?

• To solve equations

• To organize and display data

• To compare two datasets

• To calculate averages

In the two-digit example, what is the first step in creating a stem and leaf plot?

• Listing the leaves

• Drawing the plot

• Creating a key

• Ordering the data

How are the stems determined in the two-digit example?

• Using the hundreds digits

• Using the total sum

• Using the ones digits

• Using the tens digits

What does a stem of '4' and a leaf of '7' represent in the two-digit example?

• 4.7

• 7.4

• 47

• 74

In the three-digit example, what are the stems composed of?

• Ones and hundreds digits

• Hundreds and thousands digits

• Tens and hundreds digits

• Ones and tens digits

What is the range of the data in the three-digit example?

• 200 to 250

• 194 to 240

• 180 to 240

• 194 to 250

How is the key used in a stem and leaf plot?

• To compare two different plots

• To show the total number of data points

• To explain what the stems and leaves represent

• To calculate the average

What does a stem of '22' and a leaf of '5' represent in the three-digit example?

• 522

• 252

• 205

• 225

What is the final step in creating a stem and leaf plot?

• Listing the leaves

• Drawing the plot

• Adding a title

• Ordering the data

What label is used for the key in the three-digit example?

• Items

• Days

• Packages

• Years
