It is quite common to add Likert items, even though this (as both WHuber and Sal have noted) requires that we are treating them as interval data. . The two most common types of statistical measures are those for central tendency and those for dispersion. These scales group observations, like nominal data, but they also allow you to rank-order the values. This is also the reason why nominal variables can be used in regression after dummy coding them: the resulting dichotomous variables. An ordinal scale variable is one in which there is a natural, meaningful way to order the different possibilities, but you can’t do anything else.
