Life Sciences Sampling and Populations Paper
The core of biostatistics consists of the definition of a population and sampling, as they are the indicators of the fundamental concepts that are essential to understanding the statistics of the life and health sciences. The idea that a sample is illustrative of a given population, since a sample is derived from a specific, yet larger pool of information seems factually representative. Random sampling aides research in that it applies experimental design to the selection process and is the fairest means of sample collection, providing equal chance to the members of a given population being signified. Populations

Populations, as defined by Triola and Triola (2006) are “a complete collection of all elements (scores, people, measurements and so on) to be studied. The collection is complete in the sense that it includes all the subjects to be studied. To serve as an example, all Kansan 9th graders will functionally be considered for a population. The data collected from the population are referred to as parameters and therefore are descriptive. The subjects or observations within the population are labeled with an N, or in the case of the example, figuratively, would be N=6000. The first function in this type of data collection is to have identified the target population, which has been done already. Sampling

Sampling is one of the most essential notions of biostatistics, as it is the process of attaining useable information from greater groups of data called populations. “A sample is obtained from a larger population because in most instances, especially in the medical field, it is impossible to study the entire population” (Overholser & Sowinski, 2007, p. 629). The example to illustrate a sample will be the learning disabilities of the population of a classroom of Kansan 9th graders. Comparing Samples and Populations

The basis for a sample comes from...
