More

Have you felt overwhelmed, not knowing where to start with data analysis?

80% of data analysis is preprocessing. No matter how many great analysis techniques you know, you cannot get meaningful results if the data is messy. This course systematically covers essential data preprocessing techniques for practical work from start to finish using R.

This is not a lecture where you simply type along with the code. You will understand why we process data this way and how it is used in practice, helping you develop true data literacy skills.


This is a course consisting only of 'missions' without live sessions or videos.

  • From creating summary variables to utilizing GIS coordinate data

Recommended for these people

  • Beginners starting data analysis for the first time

  • Those who have learned R but found it difficult to apply in practice

  • Job seekers who were stuck on handling missing values and outliers

  • Graduate students and researchers who need to clean thesis or research data themselves

  • Office workers who feel the limitations of Excel and want to switch to R

Prior knowledge

No prior knowledge is required. However, if you have experience with basic R syntax and reading tabular data, you will find it even easier to follow along.
