In a five variable two group discriminant analysis, the following weights were derived: V₁ = .561, V₂ = .030, V₃ = .049, V₄ = .701, V₅ = -.021. The corresponding pooled standard deviations are S₁ = 4.60, S₂ = 1.23, S₃ = 10.40, S₄ = 13.23, and S₅ = 8.30. For individual 1, the values for the four variables were X₁ = 10, X₂ = 3, X₃ = 25, X₄ = 36, and X₅ = 42.
-Which variable is least important in discriminating between the two groups?

The importance of a variable in discriminant analysis can be inferred from its weight. The variable with the smallest absolute weight is considered the least important. Here, X₂ has the smallest weight of .030, making it the least important variable in discriminating between the two groups.
