**Quantitative data**is any data that is in numerical form. It is often compared to qualitative data that includes information expressed in a natural language such as English or Japanese. The following are common types of quantitative data.

## Measurements

A measurement of something physical. For example, a food safety inspection that measures the temperature of food stored in a restaurant refrigerator.## Sensors

Sensors are devices that automatically measure the physical world to create streams of data. For example, a digital camera turns electromagnetic radiation into a series of numbers using a color model.## Counts

Counting things. For example, a train station that counts the number of passengers who enter the station in real time.## Quantification

Converting qualitative human judgements into numbers. For example, asking customers to rate their satisfaction on a scale of 1 to 4.## Calculations

Mathematical calculations such as calculating gross margin based on monthly sales figures.## Estimates

Producing numerical estimates as opposed to exact calculations using algorithms, artificial intelligence, business rules or human judgement. For example, a garbage sorting robot may estimate the probability that a particular object is recyclable plastic.## Predictions

Predictions produced by algorithms, artificial intelligence or people. For example, a stock analyst may predict the future revenue and net earnings of a company.Overview: Quantitative Data | ||
