Boxplots are drawn as a box with a line inside of it, and has extended lines attached to each of its sides (known as “whiskers”). The box is used to represent the interquartile range (IQR) — or the 50 percent of data points lying above the first quartile and below the third ...
, Xₚ represent the independent variables. β₀, β₁, β₂, …, βₚ are the regression coefficients that quantify the impact of each independent variable on the dependent variable. ɛ is the error term that captures the unexplained variation in the dependent variable. The regression...
