Introduction

In today’s data-driven world, effectively handling missing data is crucial for deriving accurate insights. Whether you’re a seasoned data analyst or a beginner delving into data science, addressing missing values can drastically influence your findings. One remarkable course that addresses this vital aspect of data analysis is Coursera’s ‘Dealing With Missing Data’. In this blog post, we’ll provide an overview and review of this course, and share why we strongly recommend it.

Course Overview

The course is structured to guide participants through the comprehensive process of weighting sample surveys, particularly focusing on methods for managing nonresponse and utilizing external data for calibration purposes. Key techniques discussed include:

• Estimating response propensities
• Poststratification
• Raking
• General regression estimation
• Imputation of missing values

Learning to navigate these methods not only prepares analysts to handle missing data but equips them with essential skills to make informed decisions based on accurate assessments.

Detailed Syllabus Breakdown

1. General Steps in Weighting
