Average value = \frac{2.63+2.56+2.42+2.71+2.80}{5}

                          = 2.62\ seconds

Now,

\left | \Delta T_{1} \right |= 2.63 - 2.62 = 0.01

\left | \Delta T_{2} \right |= 0.06

\left | \Delta T_{3} \right |= 0.20

\left | \Delta T_{4} \right |= 0.09

And, \left | \Delta T_{5} \right |= 0.18

Mean absolute Error is =  \frac{0.01+0.06+0.20+0.09+0.18}{5}

Or, Mean Absolute error =  0.108\ =\ 0.11\ seconds
