Question

Kayla's class went on a field trip to an aquarium. One tank had 30 clown fish. She miscounted the total number of clown fish in the tank and recorded it as 24 fish. What is Kayla's percent error?a 6%b 25%c 30%d 30%

Answer 1

Error = Value with error - Correct value

Error = 24-30 = -6

(Note tha the minus sign means the value is less than the correct value)

$\text{ \%error = }\frac{\text{error}}{\text{True value}}\text{ x 100\%}$$=\frac{6}{30}\text{ x 100\% = 20\%}$
