Hello,

I have a couple of questions regarding the data:

Let’s say I am working on the following projects:

• Big Mart sales

• Loan Approval or credit card approval

• California House price

1. Do we always work with data that’s “Normal”? Can we work with data that’s not normal?

2. If my data has 10 attributes then which attributes should be picked to checked normality…or is there a consolidated way to check data normality for the whole of data

3. How can we transform data that’s not “normal” to normal data

4. What are the standard tests that need to be carried out on data before we begin EDA for example: Multi-collinearity etc

Thanks,

Mohit
