More about "Qualitative" and "Quantitative"
QuantitativeThe adjective "quantitative" comes from the noun "quantity." It is commonly used to describe the words "data," "information," "evidence," and "research." Quantitative information deals with numbers. It gives the quantity of something that can be measured (e.g., age, area, height, speed, temperature, time, volume, width). For example:
- The team has 7 players.
- The leaf weighs 2 ounces.
- The river is 25 miles long.
QualitativeThe adjective "qualitative" comes from the noun "quality." It is commonly used to describe the words "data," "information," and "research." Qualitative information is a description of a trait that can be observed but not measured. For example:
- The team is well prepared.
- The leaf feels waxy.
- The river is peaceful.

Converting Qualitative Information to Quantitative InformationAnalyzing qualitative information can be difficult because the descriptions are often subjective (i.e., a matter of personal opinion), and this makes it hard to do comparisons. As a result, qualitative information is not always useful for decision-making or identifying trends.
To make qualitative information easier to work with, it can be converted into quantitative information, a process which involves turning descriptions into numbers.
