# Data Cleaning for Analysts and Researchers

## Data Cleaning is a Waste of Time!

Having to correct errors and mistakes in your data is a waste of your time and it gets in the way of your analysis and getting your results.

But there are steps you can take not only to clean your data efficiently but also to minimise the errors going into your data in the first place.

When you learn the steps and the essential Excel tools you need to clean your data, you:

• become more productive and save hundreds of hours
• get your results much faster

I have been there.

Every week, while I was working as a medical statistician at one of the largest research hospitals in Europe, somebody would bring me their new project data and give me the tightest deadline to get it analysed. The problem was that I had to clean it first, which took me weeks every time. So I had to develop a system to get the data analysis-ready quickly – and to also teach researchers how to reduce the errors and mistakes in their data before they gave it to me.

This system was fine-tuned over several years of being a statistician, and is what you will be learning in Data Cleaning For Analysts and Researchers.
