Which of the following is a quantitative research method commonly used in social work?

Surveys are a quantitative research method widely used in social work because they allow for the collection of numerical data from a large number of respondents. This method involves using structured questionnaires that can be distributed either in paper form or electronically, enabling researchers to gather information on various topics such as service needs, client satisfaction, or demographic information. The standardized format of surveys facilitates data analysis using statistical techniques, which can reveal trends and patterns in the data.

In social work, the use of surveys is crucial because they help inform evidence-based practices and policy decisions by providing robust data that can be generalized to larger populations. The quantitative nature of surveys allows social workers to quantify issues, track changes over time, and assess the effectiveness of interventions, all of which are essential for enhancing service delivery and outcomes.
