There are various methods and techniques used to analyze source data, such as statistical analysis, data visualization, and machine learning. Statistical analysis is used to quantify and summarize the data, while data visualization is used to present the data in a visual format, making it easier to understand and interpret. Machine learning is used to find patterns and relationships in large data sets that are not easily visible with traditional statistical methods.
