Learn why data cleaning is important for data science. This guide covers handling missing values, outliers, and using Pandas to prepare raw data for models.

## Why data cleaning is important for your models Most people enter data science thinking they will spend all day building complex predictive models. The reality is that you spend most of your time acting as a digital janitor. If you feed a model messy data, you will get useless results. Raw data is almost always full of errors, duplicates, and missing values that can completely ruin your analysis if they are not handled correctly. In this video, we look at the essential steps for preparing your dataset: * Identifying and removing outliers that skew your statistical averages.
* Using Pandas to drop empty rows or fill missing values with mean averages.
* Converting text labels into numerical data so algorithms can process them.
* Recognizing the difference between raw noise and actual knowledge. Skipping the preprocessing stage is the fastest way to fail at machine learning. Taking the time to scrub your data ensures that your final analysis is actually grounded in reality and provides reliable insights.
