Which is NOT a characteristic of qualitative experiments?

Qualitative experiments primarily focus on descriptions and observations rather than numerical analysis. They delve into characteristics such as feelings, appearances, and experiential data, which cannot easily be quantified. The emphasis is on understanding the qualities of the subject matter, which often involves subjective interpretations based on personal feelings or perspectives. Thus, using numbers for analysis is a hallmark of quantitative research, making it distinct from qualitative approaches that seek a deeper contextual understanding through descriptive data.
