18.4 Statistical Analysis in Python and SQL
Statistical analysis is a crucial step in the process of transforming raw data into meaningful insights. Without statistical analysis, the data can be meaningless and difficult to interpret. Luckily, with the use of Python and SQL, you can perform a wide array of statistical analyses on your data, including but not limited to hypothesis testing, regression analysis, and clustering.
Hypothesis testing allows you to determine whether a certain hypothesis about your data is true or false, while regression analysis helps you identify the relationship between different variables in your data. Clustering, on the other hand, groups similar observations together, allowing you to identify patterns in your data.
By combining Python and SQL, you have access to a powerful set of tools that can help you unlock the insights hidden within your data.
