Ordinal 

The main difference in the ordinal and nominal scale is the order. In ordinal scales, the order of the values is a significant factor. An easy tip to remember the ordinal scale is that it sounds like an order. Have you heard about the Likert scale, which uses a variation of an ordinal scale? Let's check an example of ordinal scale using the Likert scale: WordPress is making content managers' lives easier. How do you feel about this statement? The following diagram shows the Likert scale:

As depicted in the preceding diagram, the answer to the question of WordPress is making content managers' lives easier is scaled down to five different ordinal values, Strongly Agree, Agree, Neutral, Disagree, and Strongly Disagree. Scales like these are referred to as the Likert scale. Similarly, the following diagram shows more examples of the Likert scale:

To make it easier, consider ordinal scales as an order of ranking (1st, 2nd, 3rd, 4th, and so on). The median item is allowed as the measure of central tendency; however, the average is not permitted.
