You are working on a dataset with income values, and you notice that a majority of incomes are clustered around $50,000, but a few are as high as $1,000,000. What transformation would be best suited to reduce the impact of these high incomes on your analysis?

  • Min-Max Scaling
  • Log Transformation
  • Z-score Standardization
  • Removing Outliers
To reduce the impact of extreme values in income data, a log transformation is often used. It compresses the range of values and makes the distribution more symmetrical. Min-Max scaling and z-score standardization don't address the issue of extreme values, and removing outliers may lead to loss of important information.
