Market research: qualitative and quantitative data

Mo and Emma discuss qualitative and quantitative data

produces that can be categorised as qualitative or quantitative data.

Qualitative data:

  • is usually expressed as opinions
  • includes descriptive information
  • is gained using open-ended questions, eg ‘What do you like about the product and why?’

It provides a business with detailed information that cannot be expressed in a graph or chart. While qualitative data gives detailed information, it can be time consuming and costly to gather and analyse.

Quantitative data:

  • is usually numerical data
  • is gathered through the use of closed questions, such as ‘yes’ or ‘no’ responses, multiple-choice options or a rating system
  • can generally be expressed in a graph or chart

It has the benefit of being simple and quick to analyse. It can also be analysed in a way that gives easy-to-understand results. However, quantitative data lacks specific opinions and doesn’t always allow a business to see exactly what its customers think.

A woman considers the opinion driven qualitative data versus the numerical quantitative data in market research.
