Question

3) A sports doctor randomly chooses 15 runners who finish the San Blás marathon, and then measures the height of each person chosen. a) Is the data obtained by the doctor qualitative or quantitative? b) Is the data discrete or continuous? c) If the researcher (doctor) uses the sample data to infer something about the population. What is the population in this case?

Answer 1

a) Quantitative data

Expalanation: The quantitative data are the measured numbers or counts while the quantitative data represents the measure class or types

Here the data of randomly selected 15 runners represents the number which is a quantitative data.

b) Continuous data

Explanation: The continuous data takes any values while discete data take only integer values. Here the height of runners can take any value hence data are continuous.

c) Population: All the runners who finish the San Blás marathon

Explanation: The researcher is interesting in the height of runners who finish the San Blás marathon hence the inference obtained from the height of sampled runners will represent the population of all runner who finish the San Blás marathon.
