Consider the following dataset:

data=[1,2,2,2,4,4,5,6,8]

We want to use a regression tree to split the dataset into two smaller branches. Use the technique of variance deduction to decide which splitting is more likely to be picked

Split1:[1,2,2,2,4,4] [5,6,8]

Split2:[1,2,2,2][4,4,5,6,8]

What is the weighted variance of the first split, rounded to two decimal places?

note:Use the formula var=(1/n)(x1-mu)^2+(x2-mu)^2+....(xn-mu)^2
