PCA Biplot

Size of dot represents position level in 2020.

Large departments are coloured individually, while small departments are grouped as ‘Other’.

The variables are:

Under the assumption that nobody is overloaded in any particular area, able to maintain a work-life balance, and excluding clear outliers, we note that teaching, research, and engaged scholarship support each other, while leadership does not necessarily help nor hinder performance.

Principal components Weights

To find a position on this plot given a set of scores:

  1. Subtract the averages from the scores
  2. Multiply by the weights of principal component 1 (PC1)
  3. Add up the 4 numbers and find the result on the x axis
  4. Repeat for principal component 2 (PC2) and find the sum on the y axis
