Most developed Western countries set the age of 60 to 65 for retirement. Being 60â65 years old is usually a requirement for becoming eligible for senior social programs. However, various countries and societies consider the onset of old age as anywhere from the mid-40s to the 70s.
Ordinal Scale Measures in terms of such values as more or less, larger or. smaller, but without specifying the size of the intervals. Example: rating scales, ranking scales, Likert-type scales. Interval Scale Measures in terms of equal intervals or degrees of. difference but without a true zero point.
We can also construct survey questions that attempt to measure on an interval level. One of the most common of these types is the traditional 1-to-5 rating (or 1-to-7, or 1-to-9, etc.). This is sometimes referred to as a Likert response scale (see Likert Scaling) .
