Data Types — Quantitative and Qualitative Data

Both qualitative and quantitative data are forms of empirical data- information which has been gathered from research observations.

Quantitative Data is data that is in numerical form (numbers and figures).

  • Disadvantages of Quantitative Data: The data is often limited to yes or no answers and rarely allows the participant to expand on their answers.

Qualitative Data is data that is in written form (usually response to a questionnaire — open question responses).
