Find the percent of error of each measurement.
0.2cm
0.4cm
Divide each number (the measurement error) by the true value. Convert that to %
Divide each number (the measurement error) by the true value. Convert that to %
0.5/0.2=2.5
0.5/0.4=1.25
To find the percent of error for each measurement, you need to compare the measured values to the expected values. The formula for percent error is:
Percent Error = (|Measured Value - Expected Value| / Expected Value) * 100
Let's calculate the percent error for each measurement:
Measurement 1: 0.2 cm
Let's assume the expected value is 0.25 cm.
Percent Error = (|0.2 - 0.25| / 0.25) * 100
= (0.05 / 0.25) * 100
= 0.2 * 100
= 20%
Measurement 2: 0.4 cm
Let's assume the expected value is 0.35 cm.
Percent Error = (|0.4 - 0.35| / 0.35) * 100
= (0.05 / 0.35) * 100
= 0.142857 * 100
= 14.29%
Therefore, the percent error for the first measurement is 20%, and for the second measurement is 14.29%.
