Scales of measurement Notes

Question – Nominal and ordinal scales of measurement

Answer – 1 Nominal – Nominal is the simplest type of scale. When the number is assigned to the purpose of identification, then these numbers are called as nominal numbers. The general examples are numbers written on jerseys of cricket players. They do not show that there is better or worse than each other. They simply serve the purpose of identification. No mathematical operation with these numbers is possible.
2 Ordinal – When the number assigned to an attribute is the property of the order, these numbers are called Ordinal scale. The general example is the merit list number. Ranking of batsmen or bowlers by the ICC is also a gradual scale. You will notice that there is an order property on this scale. Which means that the first is better than everyone else, the second is lower than the first but better than the others, and so on. But it does not guarantee that the distance between them is equal.
