For Determination of equaity we usea.Nominal scaleb.Ordinal scalec.Interval Scaled.Ratio Scale

To determine equality, specifically in the context of measurement scales, we use:

a. Nominal Scale

Nominal scales categorize data without any quantitative value. They are used for labeling variables without any order or priority.

Explanation:

• Nominal Scale: Data is classified into distinct categories. For example, types of fruits (apples, oranges, bananas) are nominal categories.
• Ordinal Scale: Measures that convey order but not the magnitude of difference.
• Interval Scale: Measures where the difference between values is meaningful, but there is no true zero (e.g., temperature in Celsius).
• Ratio Scale: Similar to interval scales but with a true zero point, allowing for the expression of relative comparisons (e.g., weight, height).

In the context of determining equality, nominal scales are suitable as they allow for categorization without implying any order or quantity, making them ideal for qualitative analysis.
