Exploring Rational Expressions: Adding and Subtracting Techniques

This video tutorial covers lesson 22 on Edpuzzle, focusing on line plots. It guides students through creating and analyzing line plots using data points. The tutorial includes practical exercises, such as plotting bug measurements and pencil lengths, and answering related questions. Students learn to identify the most and least common lengths, calculate differences, and determine total lengths. The video emphasizes careful plotting and double-checking work.

What is the purpose of using a line plot in data representation?

• To illustrate hierarchical data

• To display the distribution of data points

• To show relationships between two variables

• To compare data over time
