Numerical data (or quantitative data) is data measured or identified on a numerical scale. Numerical data can be analyzed using statistical methods, and results can be displayed using tables, charts, histograms and graphs. For example, a researcher will ask a questions to a participant that include words how often, how many or percentage. The answers from the questions will be numerical.
Examples of quantitative data would be:
- Counts
- 'there are 643 dots on the floor'
- 'there are 235 pieces of hard candy'
- 'there are 8 planets in the solar system'
- Measurements
- 'the length of this table is 1.892m'
- 'the temperature at 12:00 was 18.9 degrees Celsius'
- 'the average flow yesterday in this river was 453.2 cubic metres per second'
After the data is collected the researcher will make an analysis of the quantitative data and produce statistics.
