SOL 5.16 - Line Plots and Stem-and-Leaf Plots

Front

What is a line plot?

Back

A line plot is a graph that shows the frequency of data along a number line, using X's or dots to represent each data point.

Front

What is a stem-and-leaf plot?

Back

A stem-and-leaf plot is a method of displaying quantitative data in a graphical format, similar to a histogram, that helps to visualize the shape of the data distribution.

Front

How do you create a stem-and-leaf plot?

Back

1. Separate each data point into a 'stem' (the leading digit(s)) and a 'leaf' (the last digit). 2. List the stems in a vertical column. 3. Write the leaves next to their corresponding stems.

Front

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

Back

The 'stem' represents the leading digits of the data values.

Front

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

Back

The 'leaf' represents the trailing digit of the data values.

Front

How can you find the median from a stem-and-leaf plot?

Back

To find the median, list all the data points in order and find the middle value.

Front

What is the mode of a data set?

Back

The mode is the value that appears most frequently in a data set.

Front

How do you calculate the range of a data set?

Back

The range is calculated by subtracting the smallest value from the largest value in the data set.

Front

What is the purpose of using a line plot?

Back

A line plot helps to visualize the distribution of data points and identify trends or patterns.

Front

What is the difference between a line plot and a stem-and-leaf plot?

Back

A line plot displays data points along a number line, while a stem-and-leaf plot organizes data into stems and leaves to show frequency and distribution.
