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 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

When is it best to use a stem and leaf plot?

Back

A stem and leaf plot is best used when you want to display the shape of the data distribution while retaining the original data values.

Front

What type of data is best represented in a line plot?

Back

Line plots are best for displaying small sets of data points, especially when you want to show the frequency of each value.

Front

What is the highest value in a stem and leaf plot?

Back

The highest value is found by looking at the largest stem and its corresponding leaf.

Front

How do you find the median in 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 purpose of a line plot?

Back

The purpose of a line plot is to show how often each value occurs in a data set.

Front

What does each 'stem' represent in a stem and leaf plot?

Back

Each 'stem' represents a group of values that share the same leading digit(s).

Front

What does each 'leaf' represent in a stem and leaf plot?

Back

Each 'leaf' represents the last digit of the data points associated with the corresponding stem.
