Final answer:
Researchers collect numeric data through surveys, which is operationalized. This allows the data to be measured and analyzed statistically.
Step-by-step explanation:
Researchers collect numeric data through surveys, which is operationalized. This means that they use surveys to gather information that can be measured and analyzed using statistical methods. The data collected in surveys is often in numerical form and can be counted, allowing researchers to perform statistical analysis on the data. For example, researchers might ask yes-or-no or multiple-choice questions in a questionnaire, which collects quantitative data that can be statistically analyzed.
