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. The statistic is an estimate of a population parameter.A student can feel mathematically ready to attend College if he or she can get at least 33 out of the 36 problems correct. Sample Problems.
