Detailed explanation-1: -The DSM-IV classifies mental retardation into four stages based on severity: mild (IQ score of 50-55 to approximately 70), moderate (IQ score of 30-35 to 50-55), severe (IQ score of 20-25 to 35-40), and profound (IQ score of less than 20-25).
Detailed explanation-2: -Nominal scale is a naming scale, where variables are simply “named” or labeled, with no specific order. Ordinal scale has all its variables in a specific order, beyond just naming them. Interval scale offers labels, order, as well as, a specific interval between each of its variable options.
Detailed explanation-3: -Nominal: the data can only be categorised. Ordinal: the data can be categorised and ranked. Interval: the data can be categorised and ranked, and evenly spaced. Ratio: the data can be categorised, ranked, evenly spaced and has a natural zero.
Detailed explanation-4: -The ordinal level of measurement groups variables into categories, just like the nominal scale, but also conveys the order of the variables. For example, rating how much pain you’re in on a scale of 1-5, or categorizing your income as high, medium, or low.
