Dot Plots, Stem & Leaf Plots and frequency tables

Front

What is a dot plot?

Back

A dot plot is a simple way to display data using dots. Each dot represents one data point, making it easy to see how many times a value occurs.

Front

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

Back

In a stem-and-leaf plot, the 'stem' represents the leading digit(s) of the data, while the 'leaf' represents the last digit. This helps to organize and display data while keeping the original values.

Front

What is a frequency table?

Back

A frequency table is a way to organize data that shows how often each value occurs. It lists the values and their corresponding frequencies.

Front

How do you find the total number of data points in a frequency table?

Back

To find the total number of data points, add up all the frequencies in the frequency table.

Front

What does each dot represent in a dot plot?

Back

Each dot in a dot plot represents one individual data point or observation.

Front

How can you determine the mode from a dot plot?

Back

The mode is the value that appears most frequently in a dot plot. Look for the column with the most dots.

Front

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

Back

The purpose of a stem-and-leaf plot is to display quantitative data in a way that retains the original values while showing the distribution.

Front

How do you create a frequency table from a set of data?

Back

To create a frequency table, list all unique values from the data set and count how many times each value occurs.

Front

What is the difference between a dot plot and a frequency table?

Back

A dot plot visually displays data points with dots, while a frequency table organizes data by showing how often each value occurs.

Front

How can you use a frequency table to answer questions about data?

Back

You can use a frequency table to quickly find totals, modes, and ranges, and to answer specific questions about the data.
