Mixed methods: how the numbers and accounts connect

Creswell and colleagues' report for NIH OBSSR describes mixed methods as research that intentionally integrates quantitative and qualitative approaches to address its questions, rather than merely keeping both kinds of material side by side. [1]

General education and practical perspectives. Editorial standards.

When an article contains numbers and interview passages, look for the connection the authors actually make between them. We want to understand how the parts inform the question—not simply count how many kinds of information appear on the page.

The booking process and the unanswered questions

Imagine a fictional study of an exhibition's activity-booking process. The numerical part records how many booking forms were started and finished. The interview part explores how participating visitors understood particular instructions. The report says these questions were brought together to examine where visitors encountered difficulty.

One chart shows fewer completed forms than started forms. An interview passage describes uncertainty about whether a booking included entry to the exhibition. The authors discuss whether that theme might help interpret the chart, while acknowledging that the chart alone does not say why any form was unfinished.

Morgan notices the report also includes interview accounts from people who completed their forms but still found the wording unclear. That difference stays visible. They do not replace it with a neater story in which everyone with a question must have abandoned the form.

Find the joining point

A small reading map can contain these fields:

  • Shared question: what were the authors trying to understand?
  • Numerical part: what was measured, among whom, and when?
  • Qualitative part: what material was interpreted, and from whom?
  • Connection: where do the authors explain how the parts inform one another?
  • Tension: what does not line up neatly?
  • Unresolved point: what remains an interpretation or unanswered question?

For the fictional study, the connection is the authors' discussion of booking difficulties. Merely placing a photograph next to a chart would not answer the map's connection field. Leave that field unfilled if the report does not explain the relationship.

Do not turn disagreement into missing information

In the example, a finished form and a confusing instruction can coexist. We can retain both observations without declaring either one wrong. Likewise, do not silently treat every quoted person as part of a chart's denominator. Look for whether the report identifies the same participants, a subset, or separate groups.

This page does not supply a research design to carry out on your household. It also does not claim that mixing methods automatically makes a study stronger or establishes a cause. The booking study is entirely invented; it offers no evidence about a service or about people with ADHD.

Make space for several reading questions

A teen might ask why the instructions were interpreted differently. A parent might ask which forms entered the count. A partner might look for the passage where the authors connect those findings. An educator can help preserve an unresolved difference instead of choosing the tidiest summary. Nobody needs to contribute a private family story for these reading questions to be useful.
