Exercise

Manage skewness

We've loaded the same dataset named data. Now your goal will be to remove skewness from var2 and var3 as they had a non-symmetric distribution as you've seen in the previous exercise plot. You will visualize them to make sure the problem is solved!

Libraries pandas, numpy, seaborn and matplotlib.pyplot have been loaded as pd, np, sns and plt respectively. Feel free to explore the dataset in the console.
