In a workshop a worker measures the length of a steel plate with a Vernier callipers having a least count 0.01 cm. Four such measurements of the length yielded the following values 3.11 cm, 3.13 cm, 3.14 cm , 3.14 cm. Find the mean length, the mean absolute error and percentage error in the measured value of the length.
