Other examples of quantitative data would be the running time of the movie you saw most recently (104 minutes, 137 minutes, 104 minutes. Example 2.2Ī survey could ask the number of movies you have seen in a movie theater in the past 12 months (0, 1, 2, 3, 4. We might count the number of people who give each answer, but the answers themselves do not have any numerical values: we cannot perform computations with an answer like " Finding Nemo." This would be categorical data. When we conduct such a survey, the responses would look like: Finding Nemo, The Hulk, or Terminator 3: Rise of the Machines. We might conduct a survey to determine the name of the favorite movie that each person in a math class saw in a movie theater. Quantitative data are responses that are numerical in nature and with which we can perform meaningful arithmetic calculations. Quantitative and categorical dataĬategorical (qualitative) data are pieces of information that allow us to classify the objects under investigation into various categories. Roughly speaking, data can be classified as categorical data or quantitative data. Once we have gathered data, we might wish to classify it.
