Handle Skewed Data
A while ago, we discussed distributions of numeric columns. Depending on the types of analysis, sometimes a symmetrical distribution is preferred over a skewed one. So, in this post, I…
Common Data Issues
So far, we have discussed distribution analysis and correlation analysis when initially exploring data. One important task in this phase is to determine whether there is anything that will cause…
Correlation with Categorical Data
Previously, we have learned about tools for correlation analysis on numeric columns. By now though, you should have known that numeric is not the only type of data. In fact,…
Correlation Analysis on Numeric Data
Previously, we have learned to analyze distributions of numeric and categorical columns. However, those techniques only focus on one individual column at a time. In exploratory analysis, we have a…
Exploring Categorical Distributions
Surely after discussing distribution analysis on numeric data, we will move on to categorical data, right? Of course! In this post, we will discuss tools for performing analysis on categorical…
