Variables measured at the ordinal are often subjective ratings and rankings by human participants in relation to a stimulus or question. Ordinal variables are one echelon higher than categorical because there is a measure of distance between two points on a continuum. However, there is no "true zero" associated with ordinal level measurement and systematic error and unsystematic error may affect ordinal outcomes.
Just like with categorical variables, participants are "forced" to choose a number along the continuum. There is not a chance to be a 2.3 or a 4.9, or if you are an extremely happy person, you cannot rate yourself a 10! Thus, you do not have as much precision and accuracy in ordinal variables .
