How does this tool detect outliers?

Outliers are flagged using the standard IQR (Interquartile Range) method. Any value that falls below Q1 - 1.5*IQR or above Q3 + 1.5*IQR is categorized as an outlier.

What is the R-squared (R²) value?

R-squared (coefficient of determination) indicates the proportion of variance in the dependent variable that is predictable from the independent variable, ranging from 0 (no fit) to 1 (perfect fit).
