Frequency tables and dot diagrams

In this lesson, we will learn:

• Analyze the Frequency Table
• Understand the Dot Plot
• Convert a Frequency Table Into a Dot Plot

• Frequency table: a table showing the data values and their corresponding frequencies.
• Dot plot: a simplified version of a histogram. Each dot represents a value in that particular category.
• Dot plots are not the same as scatter plots:
• Scatter plots have a set of axes whilst dot plots do not.
• Each dot in a dot plot has a value of 1. As for a scatter plot, we need to refer to the axis for the value of a dot.
