Exploring Stem and Leaf Plots in 6th Grade Math

The video tutorial covers the concept of stem-and-leaf plots, explaining how they organize data by splitting each value into a stem and a leaf. It provides a detailed example of creating a stem-and-leaf plot using a data set of cell phone call lengths. The tutorial includes a practice exercise for viewers to try on their own, followed by an analysis of a stem-and-leaf plot to answer questions about student test scores. The video emphasizes understanding the distribution of data and interpreting the plots effectively.

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

• The middle digits of the data values

• The leftmost digits of the data values

• The rightmost digits of the data values

• None of the above

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

• The leftmost digits of the data values

• The rightmost digits of the data values

• The middle digits of the data values

• None of the above

If the smallest number in a dataset is 2 and the largest is 55, what would be the range of stems in the plot?

• 0 to 6

• 0 to 4

• 0 to 5

• 1 to 5

How would the number 14 be represented in a stem-and-leaf plot?

• 14 | 0

• 4 | 1

• 1 | 4

• 1 | 40

What should be done if a number appears twice in the data set when creating a stem-and-leaf plot?

• None of the above

• List it twice

• Ignore the second occurrence

• List it once

What does a stem of '2' and a leaf of '3' represent in a stem-and-leaf plot?

• 3.2

• 2.3

• 32

• 23

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

• To explain how to read the plot

• To identify the largest number

• To list all the data values

• To highlight the smallest number
