The data values themselves contain no information that can help you to decide. We need to take a step back go back to the basics. After randomly assigning the treatment, we can estimate the outcome variables in the treatment and control groups separately, and the difference will be the average treatment effect (ATE). Taking Action. The presence of cause cause-and-effect relationships can be confirmed only if specific causal evidence exists. However, there are a number of applications, such as data mining, identification of similar web documents, clustering, and collaborative filtering, where the rules of interest have comparatively few instances in the data. Researchers are using various tools, technologies, frameworks, and approaches to enhance our understanding of how data from the latest molecular and bioinformatic approaches can support causal frameworks for regulatory decisions.

In such cases, we can conduct quasi-experiments, which are the experiments that do not rely on random assignment. If we believe the treatment and control groups have parallel trends, i.e., the difference between them will not change because of the treatment or time, we can use DID to estimate the treatment effect. After getting the instrument variables, we can use 2SLS regression to check whether this is a good instrument variable to use, and if so, what is the treatment effect. Companies often assume that they must collect primary data, even though useful secondary data might be readily available to them.
