Answer:
The standard deviation of 2,3,6,9,10 is √10.
Explanation:
Standard Deviation:
It is a quantity expressing by how much the members of a group differ from the mean value for the group. Its symbol is б read as 'sigma'.
Formula:
б = √(Σ(x-mean)²/n)
Mean = Σx/n = (2+3+6+9+10)/5 = 30/5 = 6
Mean = 6
Σ(x-mean)² = (2-6)²+(3-6)²+(6-6)²+(9-6)²+(10-6)²
= 16+9+0+9+16
= 50
б = √(Σ(x-mean)²/n)
= √(50/5)
= √10
