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

What is the actual distance from the free throw line to the hoop in Meg's problem?

• 14 feet

• 13.5 feet

• 15 feet

• 12 feet

How do you calculate the amount of error in Meg's problem?

• Subtract the estimated distance from the actual distance

• Divide the estimated distance by the actual distance

• Multiply the estimated distance by the actual distance

• Add the estimated and actual distances

• 20%

• 15%

• 10%

• 5%

How many gumballs did Rita guess were in the jar?

• 200

• 500

• 300

• 400

What was the actual number of gumballs in the jar in Rita's problem?

• 300

• 500

• 400

• 200

How do you calculate the amount of error in Rita's problem?

• Add the guessed and actual numbers

• Subtract the guessed number from the actual number

• Multiply the guessed number by the actual number

• Divide the guessed number by the actual number

What is the percent error in Rita's gumball estimation?

• 20%

• 25%

• 35%

• 30%
