Finding Averages with Line Plots and Fractions

The video tutorial demonstrates how to create a line plot to display fractional measurements, specifically focusing on seed lengths in inches. It guides through plotting data points, verifying accuracy, calculating total lengths using multiplication, and finding the average length by dividing the total by the number of data points. The tutorial concludes with a summary and tips for solving similar problems.

What is the purpose of using a line plot in the lesson?

• To identify the color variations in seeds

• To measure the weight of seeds

• To display measurements of seeds in fractional units

• To calculate the speed of seed growth
