Quantitative variables | Statistics

Quantitative variables are variables that can assume numeric values. Examples of quantitative variables are age, revenue, speed, and number of inhabitants.

When we study a quantitative population, we collect data on quantitative variables. Quantitative variables can be discrete or continuous. Discrete variables are variables that assume integer values with gaps in between. Discrete variables, such as number of rooms in a house or number of inhabitants of a city. Discrete variables are usually the result of counting.

Continuous variables are variables that can assume any value within certain limits. Continuous variables include time, temperature and weight. Continuous variables are usually the results of those times when we measure something. Continuous variables can assume decimal values.
