Exploring Percent Error Concepts

The video tutorial explains the concept of percent of error, demonstrating how to calculate it by comparing the error to the actual value. Three examples are provided to illustrate the process, each involving different numbers and calculations. The tutorial emphasizes the importance of understanding the guess, actual value, and error to determine the percent of error accurately.

What is the percent of error when comparing an error to the actual value?

• The error is compared to the actual value.

• The error is compared to the total.

• The error is compared to the estimated value.

• The error is compared to the guess.

In the first example, what was the guess value?

• 10

• 20

• 30

• 40

In the first example, what was the actual value?

• 10

• 20

• 30

• 40

In the first example, what was the percent of error?

• 50%

• 33.3%

• 10%

• 20%

In the second example, what was the guess value?

• 24

• 22

• 20

• 18

In the second example, what was the actual value?

• 20

• 22

• 24

In the second example, what was the percent of error?

• 8.1%

• 9.1%

• 10.1%

• 11.1%

In the third example, what was the guess value?

• 105

• 95

• 90

• 100

In the third example, what was the actual value?
