Most datasets contain "missing values", meaning that the data is incomplete. Deciding how to handle missing values can be challenging! In this video, I'll cover all of the basics: how missing values are represented in pandas, how to locate them, and options for how to drop them or fill them in.

In this video, we're going to discuss how to handle missing values in Pandas. In Pandas DataFrame sometimes many datasets simply arrive with missing data, either because it exists and was not collected or it never existed. And as we can't provide null values to our Machine Learning model, we need to handle them properly. Now, let's get started. 00:00 Let's Start 01:44 Checking for Missing Values using isnull() 03:31 Filling Null Values Using fillna() 05:35 Filling Null Values Using fillna(method = 'pad') 07:05 Filling Null Values Using fillna(method = 'bfill') 11:41 Filling Null Values with the Mean, Max or Min of a Column 13:38 Dropping Null Values Using dropna() 16:12 Filling Null Values Using replace() 18:47 Filling Null Values Using interpolate() 21:50 Closing Notes Download Dataset From [🤍 Check Out the Related Article: Working with Missing Data in Pandas [🤍 Complete Pandas Tutorial [🤍 WISH TO CONTRIBUTE VIDEOS ON GEEKSFORGEEKS?

Missing Data can occur when no information is provided for one or more items or for a whole unit. Missing data is always a problem for machine learning and data analytics. Very often, it causes a lot of issues in the accuracy of model predictions because of poor quality of data caused by missing values. In these areas, missing value treatment is a major point of focus to make their models more accurate and valid. There are several useful functions for detecting, removing, and replacing null values in Pandas DataFrame.

The Pandas dropna function will allow you to easily filter out NULL or missing data. This video will show you the mechanics to apply this filter to your dataframes. After creating some fake data the video shows you how to select every other row using the .loc() method. This is how we are able to set some of the columns to be NULL. We also sneak in another handy .isna() pandas function that will return True or False if the row is missing data or if it not. If you missed my video on .isin() which is another powerful Pandas function, you can check it our here: 🤍 Even though we are able to get to the result we wanted using .isin(), it is so much more convenient to use the .dropna() function. After we get it working with isin, we then show how it can also be done using dropna and you be the judge. Where can I find the Pandas tutorials for new users? 🤍

Data can have missing values for a number of reasons such as observations that were not recorded and data corruption. Handling missing data is important as many machine learning algorithms do not support data with missing values. In this tutorial, you will discover how to handle missing data for machine learning with Python. Specifically, after completing this tutorial you will know: How to marking invalid or corrupt values as missing in your dataset. How to remove rows with missing data from your dataset. How to impute missing values with mean values in your dataset.
