Measurement+applications

=__Measurement applications__=

scientific experiments:
**Statistics** is the formal science of making effective use of numerical data relating to groups of individuals or experiments. It deals with all aspects of this, including not only the collection, analysis and interpretation of such data, but also the planning of the collection of data, in terms of the design of surveys and experiments.

**Experiment** is the step in the scientific method that arbitrates between competing models or hypotheses. Experimentation is also used to test existing theories or new hypotheses in order to support them or disprove them. An experiment or test can be carried out using the scientific method to answer a question or investigate a problem

electronic timing:
An electronic sphygmomanometer capable of timing measurement, having a key module, a controller, a memory, a manometer, a warning device and a display. The key module allows the user to input parameters such as the measuring time, interval, times, an abnormal threshold of blood pressure. The memory is controlled by the controller to store these parameters. According to a default time, a control signal is output from the controller to the manometer for performing measurement of blood pressure. Various measuring parameters and the measured blood pressure value are displayed by the display. When the measured blood pressure exceeds the threshold, a warning message is generated by the display and/or the warning device

enviromental monitoring:
**Environmental monitoring** describes the processes and activities that need to take place to characterize and monitor the quality of the environment. Environmental monitoring is used in the preparation of environmental impact assessments, as well as in many circumstances in which human activities carry a risk of harmful effects on the natural environment. All monitoring strategies and programmes have reasons and justifications which are often designed to establish the current status of an environment or to establish trends in environmental parameters. In all cases the results of monitoring will be reviewed, analyzed statistically and published. The design of a monitoring programme must therefore have regard to the final use of the data before monitoring starts.
