A critical factor about surveys is that the responses collected should be such that they can be generalized to the entire population without significant discrepancies. When calculating the Cumulative Grade Point Average of a student, the examiner uses an interval data of the student's scores in the various courses offered. You can also put data in a… Because quantitative data is not descriptive, it becomes difficult for researchers to make decisions based solely on the collected information. The singular form of data is datum, from the Latin word meaning "something given." Ratio data is a continuous data type similar to interval data, but has a zero point. Definition, Methods, Questions and Examples. Ultimately, however, all data types are stored as binary digits. Quantitative data is usually collected for statistical analysis using surveys, polls or questionnaires sent across to a specific section of a population.
