The mean is useful in determining the overall trend of a data set or providing a rapid snapshot of your data. Based on an individual application some businesses use statistical models to calculate the risk of giving insurance. For instance, let the median salary in China is almost $65,000, which means half the individual in China can earn less than $65,000, and the other half are earning more than $65,000.

Statistics is the method of conducting a study about a particular topic by collecting, organizing, interpreting, and finally presenting data. Clinical trials are time-consuming, labor-intensive, and expensive and  require the cooperative effort of physicians, patients, nurses, data managers, methodologists, and statisticians. This theme is concerned with advancing the theory, methodology, algorithmic development and application of simulation based approaches, such as Markov Chain Monte Carlo, to statistical inference. Surgical interventions pose unique challenges since surgical approaches are typically undertaken for patients with a good prognosis and may not be amenable to randomization or masking investigators and patients to the intervention, all conditions which can lead to biases.
