Four students have applied for a scholarship and only one can be selected.  The students have taken a battery of seven tests and all have exactly the same average score. The standard deviation of their scores are: Student A = 3.12, Student B = 0.27, Student C = 13.45, Student D = 6.45 If consistency of performance is a criteria for acceptance, which of the four students should be selected? And why? Justify your reasoning.
