Quantitative questions focus more on data in the numerical form to identify patterns and describe findings in charts, among other things. Data is a vast record of information segmented into various categories to acquire different types, quality, and characteristics of data, and these categories are called data types. Now according to the numerical differences, the distance between E grade and D grade is the same as the distance between the D and C grade which is not very accurate as we all know that C grade is still acceptable as compared to E grade but the mid difference declares them as equal. Qualitative (Nominal (N), Ordinal (O), Binary (B)). Binary is also a characteristic of type (it is a subset of discrete).
