Box and Whisker Plot

Box and whisker plots (boxplots) provide a standardized way of displaying data distribution based on five key statistics: minimum, first quartile (Q1), median, third quartile (Q3), and maximum. The 'box' shows the interquartile range (IQR), while 'whiskers' extend to show data range, and individual points mark outliers. This visualization is essential for comparing distributions across groups, identifying skewness, and detecting outliers in your data.

Example Visualization

Box and whisker plot comparing gene expression across 4 genotypes with significance brackets

"Use seaborn to create a box plot comparing 'Gene Expression' across 4 'Genotypes'. Overlay jittered points for individual samples. Perform pairwise t-tests against the 'WT' control and add significance brackets with stars (* p<0.05, ** p<0.01). Generate a proper example dataset to demonstrate this visualization."
