2. Data Cleaning: Remove any inconsistencies, errors, or missing values from the dataset.

3. Data Exploration: Analyze the data to understand patterns and relationships.

4. Data Visualization: Present your findings using charts, graphs, and other visual representations.

5. Data Interpretation: Draw conclusions and insights from the analyzed data.

Data analysis is a crucial process in extracting meaningful insights from raw data. The key steps involved in data analysis are essential for ensuring accuracy and reliability in decision-making. The first step is data collection, where data is gathered from various sources such as surveys, experiments, or databases. Once the data is collected, the next step is data cleaning, where any errors or inconsistencies are removed to ensure the quality of the dataset.

After data cleaning, the data is explored to identify patterns and relationships that can provide valuable insights. Data visualization plays a vital role in this step, as it helps in presenting the findings in a clear and understandable manner. Once the data is visualized, the final step is data interpretation, where conclusions are drawn and insights are generated to support decision-making.
