Stem and Leaf Plot Concepts

In this video, Mr. J explains how to create stem and leaf plots through three examples: two-digit numbers, three-digit numbers, and decimals. He demonstrates how to organize data, split values into stems and leaves, and create a key for interpretation. The video emphasizes the importance of ordering data and provides clear steps for constructing and understanding stem and leaf plots.

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

• To organize and display data

• To calculate averages

• To solve equations

• To compare two datasets

In a stem and leaf plot, what does the 'stem' represent in a two-digit number?

• The ones digit

• The tens digit

• The decimal point

• The hundreds digit

Why is it important to order data from least to greatest before creating a stem and leaf plot?

• To make calculations easier

• To highlight the largest values

• To ensure the plot is accurate and easy to read

• To reduce the number of data points

In the two-digit example, what is the stem for the number 47?

• 4

• 7

• 5

• 47

When creating a stem and leaf plot with three-digit numbers, which digits form the 'stem'?

• The hundreds and tens digits

• The hundreds digit only

• The tens and ones digits

• The ones digit

For the three-digit example, what is the leaf for the number 205?

• 20

• 0

• 5

• 2

How are decimal numbers split into stems and leaves in a stem and leaf plot?

• Ones digits as stems, tenths as leaves

• Tenths as stems, ones as leaves

• Hundreds as stems, tenths as leaves

• Tens as stems, ones as leaves

In the decimals example, what is the stem for the number 2.9?

• 9

• 2

• 29

• 0

What is the significance of a 'key' in a stem and leaf plot?

• It lists all the data points

• It explains the data source

• It clarifies what the stems and leaves represent

• It provides the title of the plot

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

• Listing all data points

• Adding a key and title

• Calculating averages

• Drawing the plot
