Quantitative research involves large samples, usually representative of a relevant population and provides data on awareness, attitudes and behaviours. Statistical analysis gives us a high degree of confidence that the findings are accurate. Here’s the most common techniques used:

Face-to-Face Interviews

Trained research interviewers will ask a pre-determined set of questions to a prescribed sample of respondents. Interviews could take place in a variety of locations and last anywhere between five to 60 minutes. The format allows visual materials, such as lists or pictures, to be shown.

Telephone Interviews

These are similar to Face-to-Face Interviews, although can offer a quicker, more cost-effective solution. Responses are often captured using CATI - Computer Assisted Telephone Interviewing.

Self-completion Questionnaires

Are sometimes used as a visible and cost effective way of consulting with large numbers of people. Options can include postal surveys or inserts in leaflets. They work well for some projects but because respondents are self-selecting they are less likely to represent the attitudes or behaviours of the wider population.

On-line Surveys

A fast and low-cost route for reaching people. Usually administered through email, website pop-ups or online panels. A great tool for some studies but there are legitimate concerns over representivity.
