| statistics Statistics (for our purposes) is defined as the calculation of meaningful data from sample data. Important statistical values include the mean, median, mode, and standard deviation. The application of statistical techniques is so pervasive that it is almost imperative that one be aquainted with some level of statistics. Applications to areas of our lives include (but are not limited to) research and quality assurance in the areas of pharmaceuticals, agriculture, as well as government and private industry. The ideal situatiion in statistics is when the sample is composed of an infinite number of elements chosen at random (i.e. a random sample). The performance of such a task would be called random sampling. It will become clear, as you do further reading, that there is no such thing as a perfectly random sample in the real world. |
