Which type of research focuses on numbers and measurable data?

Quantitative research is designed to collect and analyze numerical data, making it essential for measuring and quantifying variables. This type of research typically involves statistical methods to test hypotheses, assess relationships, and make predictions based on measurable outcomes. The emphasis on numbers allows researchers to draw conclusions that can be generalized to larger populations, making quantitative research particularly valuable in fields that require empirical evidence and statistical reliability.

Qualitative research, in contrast, focuses on understanding concepts, thoughts, or experiences expressed in non-numerical terms. Hypothetical research, while it might incorporate numerical assessments indirectly, mainly revolves around theoretical propositions rather than concrete measurements. Descriptive research, while it may use quantitative methods, can also encompass qualitative observations; it does not exclusively focus on numerical data. Thus, the clear focus of quantitative research on measurement and numerical analysis distinguishes it from the other types mentioned.
