Exploring Percent Error Concepts

The video tutorial covers the concept of percent error, explaining its similarity to percent change. It provides two examples: Meg's free throw estimation and Rita's gumball count, demonstrating how to calculate percent error using the formula y = kx. The tutorial concludes with a brief mention of future lessons on the topic.

What is percent error most similar to?

• Percent increase and decrease

• Percent of total

• Percent of a number

• Percent of a fraction

What was Meg's estimated distance from the free throw line to the hoop?

• 12 feet

• 15 feet

• 13.5 feet

• 14 feet
