Line & 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.

What is a stem-and-leaf plot?

Back

A stem-and-leaf plot is a method of displaying quantitative data in a graphical format, where each number is split into a 'stem' (the leading digit) and a 'leaf' (the trailing digit).

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

Back

1. Separate each data point into a stem and a leaf. 2. List the stems in a vertical column. 3. Write the leaves next to their corresponding stems.

Front

What is the purpose of using a line plot?

Back

Line plots help visualize the distribution of data points and make it easy to see how often each value occurs.

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

Back

Stem-and-leaf plots provide a way to display data while retaining the original values, making it easy to see the shape of the data distribution.

Front

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

Back

To read a stem-and-leaf plot, look at the stems on the left and combine them with the leaves on the right to form the original data values.

Front

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

Back

The 'stem' represents the leading digit(s) of the data values.

Front

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

Back

The 'leaf' represents the trailing digit(s) of the data values.

Front

How can you compare two sets of data using line plots?

Back

You can compare two sets of data by overlaying their line plots on the same number line to see differences in frequency and distribution.

Front

What is the first step in creating a line plot?

Back

The first step is to determine the range of data values and create a number line that includes all values.
