Before diving into specific tools, it’s essential to understand the type of data you have:

  1. Categorical Data: Data that can be divided into distinct groups or categories (e.g., types of products, customer segments).
  2. Numerical Data: Data that represents quantities and can be measured (e.g., sales figures, profit margins).
  3. Time Series Data: Data points indexed in time order (e.g., monthly sales, stock prices over time).
  4. Relational Data: Data that shows relationships between variables (e.g., correlation between marketing spend and sales).
