Square root transformation

In the video you learned that the logarithmic function can be used to flatten out differences between values. An alternative for the logarithmic function is the square root: this function will also flatten out differences between values but the effect is slightly weaker.

Given is a very small basetable with population 4 donors and the predictive variable "donations" that has the total amount of donations last year. In this exercise you will add the logarithmic and square root transformation to this basetable and compare the effect of both transformations.

Instructions
100 XP
  • Add the log transformation of the variable "donations" to the basetable.
  • Add the square root transformation of the variable "donations" to the basetable.
  • Print the basetable with these added features.
