Variable types : clarification

According to the getting started doc ( , JASP distinguishes 4 variable types: nominal, nominal text, ordinal, continuous. Ordinal variables are "categorical variables with an inherent order". I was wondering whether ordinal variables could also refer to quantitative variables with a discrete scale (e.g., number of words recalled in a memory experiment). Thanks for your help!


  • Yes, that could in general be the case, although your specific example looks like a ratio scale. Of course you may be interested in an underlying psychological process that has a monotonic relation to the number of words; in this case an analysis assuming an ordinal scale is safest.

  • Thanks for the clarification E-J!
