Make a boxplot of the Credit River flow data for the month of April.To find a data transform which makes the boxplot more symmetric,first square the data (eg.let c4=c1**2),then take the square root of the data (eg.let c4=sqrt(c1)),and finally take the natural log of the data (eg.let c4=log(c1)) where c4 now contains the transformed April data.Which transform makes the boxplot more symmetric?
a.Square Transform
b.Square Root Transform
c.Natural Log Transform
