Definition
Nominal level of measurement is the lowest level of measurement where variables are categorized into distinct groups or categories based on their characteristics or attributes.
Analogy
Think about different types of fruits at a grocery store being sorted into different bins based on their names (apples, oranges, bananas). Each fruit belongs to one category without any inherent order or ranking - just like nominal level data.
