Step-by-step explanation:

In statistics, the level of measurement used for a variable determines the what summary statistics and analysis are possible. There are three types of level of measurement.

Nominal

Ordinal

Interval/ Ratio

The nominal is the most basic level of measurement. It is known as categorical or qualitative. Examples includes, numbers,color, sex.  Nominal can be stored as a word or text  or given a numerical code.However, the number do not imply order. They are usually expressed in percentage

Ordinal  are variables based on ranks, they are usually have a meaningful order but the intervals between the variables may not be equal. They are usually expressed in frequencies.

The interval/ratio level of measurement  is the most precise level of measurement. Data can be measured and ordered. Examples include, number of customers, age, weight or size. Interval / Ratio data is also known as scale, parametric or quantitative. Interval / Ratio can be discrete  with whole numbers or continuous with fractional numbers.
