Percent Error

The video tutorial explains the concept of boiling point and percent error. It begins with Tiffany's experiment to measure the boiling point of water, which she found to be 210 degrees Fahrenheit instead of the expected 212 degrees. The tutorial then introduces the concept of percent error, explaining how it measures the difference between observed and actual values. Using Tiffany's experiment as an example, the video demonstrates the calculation of percent error, resulting in a 0.94% error. The lesson concludes by summarizing the steps to calculate percent error.

What was the boiling point of water that Tiffany observed in her experiment?

• 200 degrees Fahrenheit

• 210 degrees Fahrenheit

• 220 degrees Fahrenheit

• 212 degrees Fahrenheit

What is the formula for calculating percent error?

• Actual value minus observed value, divided by actual value, times 100

• Actual value minus observed value, divided by observed value, times 100

• Observed value minus actual value, divided by observed value, times 100

• Observed value minus actual value, divided by actual value, times 100

What is the absolute value of the difference between Tiffany's observed and actual boiling points?

• 3

• 2

• 1

• 0

After calculating the absolute difference, what is the next step in finding the percent error?

• Multiply by 100

• Divide by the observed value

• Divide by the actual value

• Subtract from 100

What was the final percent error in Tiffany's experiment?

• 1.94%

• 0.94%

• 3.94%

• 2.94%
