Because the variable types are different in each case, the statistical test used to calculate results will be different as well.

Detailed explanation-2: -An ordinal variable is a categorical variable for which the possible values are ordered. Ordinal variables can be considered “in between” categorical and quantitative variables. Thus it does not make sense to take a mean of the values.

Detailed explanation-3: -Ordinal Scale is defined as a variable measurement scale used to simply depict the order of variables and not the difference between each of the variables. These scales are generally used to depict non-mathematical ideas such as frequency, satisfaction, happiness, a degree of pain, etc.

Detailed explanation-4: -Examples of ordinal variables include: socio economic status (“low income”, ”middle income”, ”high income”), education level (“high school”, ”BS”, ”MS”, ”PhD”), income level (“less than 50K”, “50K-100K”, “over 100K”), satisfaction rating (“extremely dislike”, “dislike”, “neutral”, “like”, “extremely like”).
