Students who successfully complete this could should be able to: critically consume statistically-based results reported in popular media, recognizing whether reported results reasonably follow from the study and analysis conducted.A sample is defined as a set of selected individuals, items, or data taken from a population of interest. A characteristic (usually numeric) that describes a sample is referred to as a sample statistic. NOTE: Inferential statistics are used to help the researcher infer how well statistics in a sample reflect parameters in a population.

Definition 3. A quantitative measure of a sample data is called a statistic. So, any constant that we compute from a sample is a statistic.However, there’s a shortcut to finding 5 choose 3. The combinations formula is: nCr = n! / ( (n – r)! r!) n = the number of items. r = how many items are taken at a time. The ! symbol is a factorial, which is a number multiplied by all of the numbers before it. For example, 4! = 4 x 3 x 2 x 1 = 24 and 3! = 3 x 2 x 1 = 6.
