How to Visualize Skewness in Your Data
Visualizing skewness in data helps to understand the distribution and identify if the data is asymmetrical, leaning toward the left or right. This is important because skewness can influence the performance of statistical models, as many techniques assume a normal distribution. Below are the most common methods to visualize skewness: 1. Histogram Histograms are one…
