Exploratory techniques are also important for eliminating or sharpening potential hypotheses about the world that can be addressed by the data you … Sometimes it is dome before diving into the modeling. Results. Summarize the missing values in the data. This week we are working on the chronic kidney disease (CKD) dataset from Kaggle. Etc. Check the distribution. There are various steps involved when doing EDA but the following are the common steps that a data analyst can take when performing EDA: Import the data. This was the first Kaggle competition that I participated. To build a good kaggle profile, one needs to work on the data and build high-quality Python or R notebooks in the form of projects and tell a tale through the data.
