Numerical or Nonnumerical
Type of Data Set
Ages of people attending a concert
Ages are numerical measurements
Quantitative data
Heights of skyscrapers in a city
Heights are numerical measurements
Quantitative data
Populations of counties in a state
Number of people is a numerical measurement
Quantitative data
