Looking at Quantitative Data

Consider the statistical question: How old are the winners of the Best Actress and Best Actor awards at the Academy Awards (more commonly known as “the Oscars”)?[1]

Quantitative data are always numbers. Quantitative data are the result of counting or measuring attributes of a population. Amount of money, pulse rate, weight, number of people living in your town, and number of students who take statistics are examples of quantitative data. Quantitative data may be either discrete or continuous.

  • All data that are the result of counting are called quantitative discrete data. Quantitative discrete data can be represented by non-integer values if they still represent a fixed list of values like 1.0, 1.5, 2.0… etc
  • Continuous quantitative data, on the other hand, can take on any value within a given range. These data points can be measured with a high degree of precision.
