Quantitative observation, also called quantitative data, includes information that includes numbers, measurements and statistics. Quantitative data serves as a tool to measure data in many areas, including algebra in mathematics. Quantitative data complements the use of qualitative data, which uses descriptions, adjectives and linguistic elements to describe objects and images.

Although qualitative and quantitative data differ in methods used to describe and observe the surrounding world, they provide equally valuable knowledge to describe subjects and provide useful information on them. Quantitative data takes a practical and realistic approach to documenting data, in contrast to qualitative data, which explains information in a more abstract method. This data typically uses several methods of evaluation, including numbers and measurements. Factors such as length, height, volume, area, speed, temperature, sound, humidity level, amount of precipitation, numbers of people, ages and gender are factors used to describe quantitative data. In essence, quantitative data expresses a precise measurement of quantity using the most appropriate and logical methods. Many different types of objects, such as paintings, cups of coffee and students in classrooms demonstrate quantitative data. In paintings, quantitative analysis includes measurements of height and width of paintings. Quantitative data of coffee includes temperature of coffee, amount of liquid in ounces and price of the beverage. In contrast to quantitative data, qualitative analysis describes scent, texture and taste.
