What does inferences mean in statistics?
Statistical inference is the process of drawing conclusions about an underlying population based on a sample or subset of the data. In most cases, it is not practical to obtain all the measurements in a given population.
How do you write an inference in statistics?
Statistical Inference Procedure
- Begin with a theory.
- Create a research hypothesis.
- Operationalize the variables.
- Recognize the population to which the study results should apply.
- Formulate a null hypothesis for this population.
- Accumulate a sample from the population and continue the study.

Medicine often uses probabilistic statistics that could be far away from the scientific method. Data are used and analysed in order to highlight trends or to make a prevision for the validity of a diagnostic method, a therapy or a prognosis for a disease.

What is sample inference?
The use of randomization in sampling allows for the analysis of results using the methods of statistical inference. Statistical inference is based on the laws of probability, and allows analysts to infer conclusions about a given population based on results observed through random sampling.
How does statistics affect healthcare?
Health statistics are used to understand risk factors for communities, track and monitor diseases, see the impact of policy changes, and assess the quality and safety of health care. Health statistics are a form of evidence, or facts that can support a conclusion.
