Qualitative Vs Quantitative Data

The type of data plays a vital role in data analysis. There are two types of data: quantitative and qualitative data. The prime difference between the two is the measureability of each. While quantitative data can be measured and expressed in numbers, qualitative data cannot be measured or expressed in numerical form.

Quantitative data comprises quantities and numbers, like sales figures, percentage revenue, and conversion rate. These data types can be analyzed, and insights can be drawn from them via statistical and mathematical techniques. These data types have real-life applications in sectors ranging from finance and marketing to social sciences.

Qualitative data comprises non-numerical information that consists of factors like qualities, characteristics, and attributes. This type of data can be collected via interviews, focus groups, observations, and surveys and give insights about the ‘how’ and ‘why’ aspects of behaviors and experiences. Therefore, this approach is more subjective than quantitative data.
