Quantitative or Qualitative?

"Quantitative" and "qualitative" are easy to confuse. "Quantitative" is used with numbers, and "qualitative" is used for features or qualities.- Quantitative. Quantitative information (from "quantity") tells us the number for something that can be measured. For example:

Converting Qualitative Information to Quantitative Information
Analyzing 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.
