Qualitative analysis

As explained in Effective Data Analysis

Qualitative analysis is the synthesis, interpretation, and examination of non-numerical information.

Qualitative analysis synthesizes, examines, and interprets non-numerical information, especially unstructured or free-form language recorded as text. section 3.2.1

It connects analytical findings with people’s experiences through interviews, focus groups, free-text survey responses, and language-processing methods. Quotes and themes can make quantitative results more concrete for stakeholders. section 3.2.1

Choose methods according to the size and purpose of the inquiry:

  • Use one-to-one interviews and focus groups as starting points for small-sample research. section 3.2.1
  • Use natural language processing, including sentiment analysis and topic modeling, to generate insights from larger text samples. section 3.2.1
  • Set clear expectations about the deliverable and how its interpretation was derived. section 3.2.1

Small-sample methods can struggle with generalizability when used independently, so qualitative findings will often need quantitative complements. Automated language methods can also confuse stakeholders unfamiliar with them. section 3.2.1

What you can do after
Evaluate qualitative evidence, relate it to quantitative findings, and explain its derivation to stakeholders.
How it connects
