koguslik

Koguslik is an Estonian adjective meaning quantitative, relating to quantities, numbers, or measurable data. In academic usage it describes data, methods, or analyses that rely on numeric values and statistical techniques, as opposed to qualitative approaches (kvalitatiivne) that focus on meanings, experiences, and non-numeric descriptions. The term is commonly used in research design, data collection, and data analysis.

In koguslik uurimus, researchers collect structured data through surveys, experiments, or secondary data sources. Data are typically numeric and suitable for statistical analysis. Common data types include nominal, ordinal, interval, and ratio scales. Descriptive statistics summarize data, while inferential statistics make inferences about populations. Analyses may involve t-tests, ANOVA, correlation, regression, and other statistical models. The aim is to quantify relationships, test hypotheses, and generalize findings to larger populations.

In practice, koguslik methods emphasize standardization, reproducibility, and objectivity. They often require larger sample sizes and rigorous measurement procedures to ensure reliability and validity. Koguslik analysis complements qualitative approaches, with mixed-methods designs integrating numerical data and contextual insights.

Terminology notes: in Estonian, kvantitatiivne is a common direct equivalent of quantitative, while koguslik remains widely used in some disciplines and in general language. See also kvalitatatiivne, kvantitatiivne, statistics, and research methodology.
