Quantitative vs. qualitative data

 

There are two general types of information: quantitative and qualitative data. The difference between quantitative and qualitative data is the nature of the data itself. Quantitative data has to do with quantities and numbers, or data that can be counted, such as how many, how much, and how often. On the other hand, qualitative data has to do with the characteristics of whatever it is being considered, and involves information about people’s feelings, thoughts, perceptions, opinions, behaviors, beliefs, attitudes and observations.

Both quantitative and qualitative data can be useful depending on your purposes. Here’s a handy table that contrasts the two types of data for easy reference:
