Key Concepts

Variable Identification

A variable is a characteristic or attribute that is measured in a study. In this context, the variable is the miles per gallon (mpg) achieved by each new hybrid small car, which is the measurement of fuel efficiency.

Quantitative Variable

A quantitative variable is one that is measured on a numerical scale and represents a quantity. Here, mpg is a numerical measurement that represents how many miles a car can travel per gallon of fuel, making it a quantitative variable.

Population and Sampling

The implied population refers to the entire group that the study intends to generalize its findings to. In this case, it is all new hybrid small cars that are available in the market, with the sample being the individual cars whose mpg was measured to estimate the fuel efficiency for the whole group.
