In probability theory, the sample space (also called sample description space, [1] possibility space, [2] or outcome space [3]) of an experiment or random trial is the set of all possible outcomes or results of that experiment. [4] A sample space is usually denoted using set notation, and the possible ordered outcomes, or sample points, [5] are ...
A probability space is a mathematical triplet that presents a model for a particular class of real-world situations. As with other models, its author ultimately defines which elements , , and will contain. The sample space is the set of all possible outcomes. An outcome is the result of a single execution of the model.
It is used for alert (conscious) people, but often much of this information can also be obtained from the family or friend of an unresponsive person. In the case of severe trauma, this portion of the assessment is less important. A derivative of SAMPLE history is AMPLE history which places a greater emphasis on a person's medical history.
Simple random sample. In statistics, a simple random sample (or SRS) is a subset of individuals (a sample) chosen from a larger set (a population) in which a subset of individuals are chosen randomly, all with the same probability. It is a process of selecting a sample in a random way. In SRS, each subset of k individuals has the same ...
Spinoff is a NASA publication featuring technology made available to the public. Since 1976, NASA has featured an average of 50 technologies each year in the annual publication, and Spinoff maintains a searchable database of these technologies. When products first spun off from space research, NASA presented a black and white report in 1973 ...
The Standard addition method, often used in analytical chemistry, quantifies the analyte present in an unknown. This method is useful for analyzing complex samples where a matrix effect interferes with the analyte signal. In comparison to the calibration curve method, the standard addition method has the advantage of the matrices of the unknown ...
Extensive properties. An extensive property is a physical quantity whose value is proportional to the size of the system it describes, [8] or to the quantity of matter in the system. For example, the mass of a sample is an extensive quantity; it depends on the amount of substance. The related intensive quantity is the density which is ...
Research North America. The sample for each week's OMNITEL wave consists of 1,000 completed interviews, made up of male and female adults (in approximately equal number), all 18 years of age and over. All interviews are conducted by telephone from three GfK phone centers: Twin Falls & Rexburg, ID and Cebu, Philippines.
