Z scores are then calculated using the percentage values for each ward under each indicator. For the unemployment and overcrowding variables, the logged versions are used instead.
Z scores= (percentage – mean romania rcs data of all percentages)/ SD of all percentages
Z scores of logged variables= (log percentage – mean of log percentages)/ SD of log percentages
Total of the 4 Z scores=
Through the sources found it wasn’t perfectly clear how to calculate Z scores from the logged variables. There was no clarification about whether to take the mean and standard deviation of the percentages after they are logged or before. Taking information from different sources gave a good idea of the correct formula, however, the important next step is to test this formula against existing scores to ensure it is correct before continuing the process of this project.
