Show moreA 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
From the sample data, we can calculate a statistic. A statistic is a number that represents a property of the sample. For example, if we consider one math class to be a sample of the population of all math classes, then the average number of points earned by students in that one math class at the end of the term is an example of a statistic.Moving average is a statistical computation used to examine data points by calculating a series of averages of different subsets of the entire data set. ...
