# Quantitative research

From Clinfowiki

Qualitative and quantitative research differ in several significant ways. One difference is that quantitative studies usually require a larger sample size. Qualitative studies can research "Saturation" much sooner, the point where additional information adds very little value as all of the major themes have been identified. Quantitative studies, due to their more objective nature and larger sample size, can often be generalized to a larger population, whereas qualitative studies are specific to the group studied.
