The versatility of the method makes it an indispensable primary source of data and a supplement to other methods. Making direct observations of simplistic phenomena can be a very quick and effective way of collecting data with minimal intrusion. Data collection methods Surveys, interviews and focus groups are primary instruments for collecting information. In a cross-sectionalstudy, you only collect data on observed relationships once. These three manual, paper- based types have corresponding electronic methods: more useful when a behavior needs to be evaluated on a continuum.They Close ended survey questions fall under quantitative primary data collection.
