Longitudinal studies repeatedly observe the same sample population, while cross-sectional studies are conducted with different research samples. While cross-sectional studies give you a snapshot of the situation in the research environment, longitudinal studies are better suited for contexts where you need to analyze a problem long-term. A cross-sectional study is a type of observational study in which the researcher collects data from variables at a specific moment to establish a relationship among them. Retrospective studies have several chances of bias because first-hand information is not possible in this case. Despite their different approaches to data gathering and analysis, there are a number of similarities between quantitative and qualitative observation methods.

For example, if you wanted to examine whether first-time moms who have an elective induction are more likely to have a cesarean birth than first-time moms who go into labor naturally, the independent variables would be elective induction and go into labor naturally (because they are the variables that vary) and the outcome variable is cesarean section. Even if you find a strong relationship between elective inductions and an increased likelihood of cesarean birth, you cannot state that elective inductions cause cesarean births because we have no control over the variables.
