Statistical Features

Introduction to statistical features

Features that provide numerical information about the given data are known as statistical features. They help to extensively explore the nature and properties of data. The following are some features that will be discussed here:

• Mean/Median

• Standard deviation (STD)

• Quantiles

• Skewness

The above properties of data provide information that helps in the examination, inference, and prediction. These properties can only be applied to quantitative parts of the data.

Mean/Median

• Mean: This is the average of the dataset computed by dividing the sum of numbers with their quantity.

• Median: This is the exact middle value of a dataset. The data needs to be sorted first to get this measure.

In statistics, the median value is preferred to be used over the mean value because sometimes the mean value can get affected by exceptionally small or large outliers which might bend the mean in the wrong direction. Therefore, the median value is considered as it provides ...
