A coach is comparing the scoring consistency of two cricket players in five consecutive matches.
Player A (runs): 48, 52, 55, 45, 50
Player B (runs): 20, 100, 15, 90, 25
(i) Calculate the range of runs for each player.
(ii) Compute the standard deviation of runs for each player (show all working).
(iii) Using the numerical results of parts (i) and (ii), advise the coach which player is more consistent. Support your answer with clear reasoning based on both measures.
