Imputation and outlier detection are the two statistical methods we use for data cleaning in a machine learning project.

Not every variable or observation is relevant while modeling.

The process of data selection is where we reduce the data to make it relevant for predictions..

## How do you do data science statistics?

## For this purpose, one can use statistical sampling techniques such as Random Sampling, Systematic Sampling, Clustered Sampling, Weighted Sampling, and Stratified Sampling.

- Mean.
The mean, also known as the average, is a central value of a finite set of numbers.- Standard Deviation
- Covariance
- Correlation

## How statistical tests are used in data science?

Perform a statistical test that suits our data.

Check the resulting p-Value.

If the p-Value is smaller than our significance level, then we reject the null hypothesis in favor of our alternative hypothesis.

If the p-Value is higher than our significance level, then we go with our null hypothesis..
