What type of research collects and reports data primarily in numerical form?

Quantitative research focuses on collecting and analyzing numerical data to understand patterns, correlations, and effects within specific variables. This type of research employs statistical methods to determine relationships and test hypotheses, enabling researchers to derive conclusions based on measurable evidence. The emphasis on numerical data allows for objective comparisons and can lead to generalizable results across larger populations.

Qualitative research, in contrast, gathers non-numerical data, such as opinions and experiences, to gain insights into underlying motivations and behaviors. Descriptive research primarily aims to describe characteristics or functions without identifying relationships or cause-and-effect dynamics. Analytical research involves examining existing data to draw new conclusions but is not exclusively based on numerical data. Hence, the distinguishing feature of quantitative research is its reliance on numerical data that can be quantified and statistically analyzed.
