The matrix \(N\) gives the number of tokens collected by two groups in two activity categories. The matrix \(P\) gives the points per token in those categories under two scoring rules; its row order matches the category order in \(N\)

N = \begin{bmatrix} 1 & 2 \\ 9 & 5 \end{bmatrix}

P = \begin{bmatrix} 4 & 9 \\ 4 & 8 \end{bmatrix}
