With current technologies, it is possible for almost anyone to distill quantitative data into text, or more visually, into a table or chart. Quantitative data can help you see the big picture. Quantitative research methods emphasize objective measurements and the statistical, mathematical, or numerical analysis of data collected through polls, questionnaires, and surveys, or by manipulating pre-existing statistical data using computational techniques.

The facts provide statistics that are suitable to consider when difficult decisions must get made. Ordinal: Quantitative data at the ordinal level of measurement can be ordered, however, differences between values are meaningless. Quantitative data can be counted, measured, and expressed using numbers. It is primarily used to discover and gain an in-depth understanding of individual experiences, thoughts, opinions, and trends, and to dig deeper into the problem at hand.
