n=0
In statistics, "n=0" indicates that there are no observations or data points in a given study or analysis. This means that the sample size is zero, which can occur in various situations, such as when a survey fails to gather responses or when a specific group is not represented. Without any data, it is impossible to draw conclusions or make inferences about the population being studied.
Having an n=0 can significantly impact research findings, as it limits the ability to assess trends, relationships, or effects. Researchers often aim for a larger sample size to ensure that their results are reliable and valid. In cases where n=0 is encountered, it may prompt a reevaluation of the research design or methodology to improve data collection efforts.
