I want to correlate the level of anxiety of workers (normal, moderate, severe, etc.) and their job performance (very high, high, moderate, etc.) what should I use?

  • What do you like about [tag:spearman-rho] that you used as a tag? – Dave Jul 29 '21 at 15:27
  • HI Dave, May I ask. What stat tool should I use to correlate the level of anxiety of workers (normal, moderate, severe, etc.) and their job performance (very high, high, moderate, etc.) what should I use? – Mars Ares Jul 29 '21 at 15:29
  • @MarsAres See Software implementations for a few options. – Galen Jul 29 '21 at 15:35
  • Thanks, Galen, I'm just a bit confused about whether to use Pearson or Spearman rho. thank a lot – Mars Ares Jul 29 '21 at 15:39
  • @MarsAres Spearman's rho is Pearson's r calculated on the ranks of the data, rather than on the data itself. It appears from your question that the levels of your random variables have an order type, but not necessarily scaling properties, so Spearman's rho is likely more appropriate for your data. – Galen Jul 29 '21 at 15:47
