Statistical tests are used to test the fit between a hypothesis and the data. [1] [2] Choosing the right statistical test is not a trivial task. [1] The choice of the test depends on many properties of the research question. The vast majority of studies can be addressed by 30 of the 100 or so statistical tests in use. [3] [4] [5]
Where there is a health care facility with laboratories, tests are divided into either general tests or disease-specific tests for clinical laboratories, and disease-specific tests for blood screening laboratories. [5] For each group of tests, the EDL specifies the test's name, purpose, assay format and type of specimen. [6]
However, "biostatistics" more commonly connotes all applications of statistics to biology. [2] Medical statistics is a subdiscipline of statistics. It is the science of summarizing, collecting, presenting and interpreting data in medical practice, and using them to estimate the magnitude of associations and test hypotheses.

N/A Crash test: A form of destructive testing usually performed in order to ensure safe design standards in crashworthiness: N/A Moose test: Performed to determine how well a certain vehicle evades a suddenly appearing obstacle. 1970s Nondestructive ...
The specificity of the test is equal to 1 minus the false positive rate. In statistical hypothesis testing, this fraction is given the Greek letter α, and 1 − α is defined as the specificity of the test. Increasing the specificity of the test lowers the probability of type I errors, but may raise the probability of type II errors (false ...
Epidemiology is the study of factors affecting the health and illness of populations, and serves as the foundation and logic of interventions made in the interest of public health and preventive medicine. Forensic statistics is the application of probability models and statistical techniques to scientific evidence, such as DNA evidence, and the ...
The tests are classified by speciality field, conveying in which ward of a hospital or by which specialist doctor these tests are usually performed. The ICD-10-CM is generally the most widely used standard by insurance companies and hospitals who have to communicate with one another, for giving a overview of medical tests and procedures.
