PERCENT ERROR Percentage Error is all about comparing a guess or estimate to an exact value.
PERCENT ERROR Percentage Error is all about comparing a guess or estimate to an exact value. SAMPLE PROBLEM I estimated 260 people, but 325 came. Subtract approximate value from the exact value Take the absolute value. The error is 65 Divide the error by the exact value And make it a percentage:
A man measured his height and found 6 feet. However, after he carefully measured his height a second time, he found his real height to be 5 feet.What is the percent error the man made the first time he measured his height? amount of error = 6 - 5 = 1The accepted value is the man's real height or the value he found after he carefully measured his height, or 5 So, percent error = 1/5=20%
12.5% -16.67% -10.71%
