Unlike qualitative studies, quantitative studies collect numerical data, such as age, weight, temperature, blood pressure measurements etc. Quantitative study designs fall into two categories, experimental or observational, depending on whether or not an exposure or intervention was introduced to the study cohort by the researchers. Experimental studies include randomised controlled trials or non-randomised trials. Observational studies include cohort studies, case-control studies, cross-sectional studies, and case studies.

Quantitative study designs include case studies, case-control studies, cohort studies, cross-sectional studies, RCTs, and systematic reviews.

REDCap (Research Electronic Data Capture) is a secure web application for building, sending, and managing online surveys. REDCap can be used to collect any type of data, however, it is specifically geared to support data capture for research studies.
REDCap allows for form customisation with HTML and CSS, survey logic, file attachment, data export and import, collaboration with external researchers, and sending email and text alerts.
Unlike, Excel or Survey Monkey, REDCap meets the requirements for security, privacy, data quality, and data auditing and should be used when conducting health research. Many ethics committees are aware of and approve of the use of REDCap.
