Nominal Scales
Nominal scales sounds like names, they are referred as Labeling a sample or population into groups or subcategories by a name or a label. This classification is based on a common characteristic, feature, quality or attribute. Nominal scales are used in qualitative research and measure non numerical concepts. This scale is the simplest scale and only indicates categories but not ordered categories. This is called as categorical scale. They have no numerical value and cannot be quantified into numbers

Interval scales not only categorize the objects or responses in order but also depict the exact value between equal gaps. This scale of measurement has a beginning and ending point and has been divided into equally spaced intervals or units. There can be variation in starting and ending points and intervals between them can be different at different scales. The interval differences are meaningful but we can’t defend ratio relationships. These intervals are the units which can be measured exactly, and is accepted as standard units of measurement that can be infinitely divided. There is no true zero in this …show more content…
