1
What transformation should be done to the data set, with its residual shown below, to linearize the data?
take the log of the dependent variable
multiply the dependent variable by a constant k.
Add 
multiply the independent variable by
Nothing, the data set is already linear
Explanation
Taking the log of a data set whose residual is nonrandom is effective in increasing the correleation coefficient and results in a more linear relationship.
