Statistical analysis is a key component in understanding data, with visualizations like boxplots commonly used. However, boxplots can be misleading if not interpreted carefully, as they can oversimplify data distributions and hide critical details. Additional visual tools such as stripplots and violinplots should be considered to show the full distribution of data, especially when dealing with datasets where quartiles appear similar but underlying distributions are different. These tools help to reveal gaps and variations that boxplots might obscure, making for a more robust interpretation. Another crucial aspect of statistical analysis involves addressing missing data, which is a frequent challenge in real-world datasets. The nature of missing data—whether it's completely at random (MCAR), missing at random (MAR), or missing not at random (MNAR)—significantly impacts how it should be handled. Identifying the mechanism behind missing data is critical for choosing the appropriate analytical strategy, preventing bias in the analysis. Additionally, robust regression methods are valuable as they are designed to handle outliers and anomalies that can skew results in traditional regressions.
