An experiment is performed in an ideal condition to find out the velocity of a particle obeying the equation S=vtS=vt where the distance travelled (S)(S) inside    a labeled glass tube by a particle with an uniform velocity (v)(v) is measured with respect to time taken (t)(t). The data collected by repeating the experiment    five times is shown in the table below   If we use the method to minimize the squared sum error, what is the most likely velocity of the particle among the given options?    2.5  1.5  2  1
