How to Detect Outliers with Z Score | Clearly Explained
Welcome to the twelfth video of the series "Build your First Machine Learning Project". In this, we'll see how to detecting outliers with Z Score.
Notebook / Code link: https://github.com/machinelearningplu...
Z-score is a way to standardize the data to standard scale i.e. how far the data point is from the mean. The z-score can come positive or negative based on the help of mean and standard deviation values.
The data point away from the mean with some standard deviation is called a z-score.
So let's understand it.
