Range=12-3=9
Mean=(12+6+7+3+10)/5=7.6
Mean Deviation=[(12-7.6)+(7.6-6)+(7.6-7)+(7.6-3)+(10-7.6)]/5 = 13.6/5=2.72
Standard Deviation=sqrt=[(12-7.6)^2(7.6-6)^2+(7.6-7)^2+(7.6-3)^2+(10-7.6)^2]/(5-1)=sqrt[19.36+2.56+0.36+21.16+ 5.76]/4=sqrt[12.3]=3.51
Mean=(12+6+7+3+10)/5=7.6
Mean Deviation=[(12-7.6)+(7.6-6)+(7.6-7)+(7.6-3)+(10-7.6)]/5 = 13.6/5=2.72
Standard Deviation=sqrt=[(12-7.6)^2(7.6-6)^2+(7.6-7)^2+(7.6-3)^2+(10-7.6)^2]/(5-1)=sqrt[19.36+2.56+0.36+21.16+ 5.76]/4=sqrt[12.3]=3.51
