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.Math is often called the universal language. Learn all about mathematical concepts at HowStuffWorks.

Twelve students were given a math test, and the times (in minutes) to complete it are listed below. Find the range of these times. 10, 9, 12, 11, 8, 15, 9, 7, 8, 6, 12, 10. ANSWER BOX: min. RESULTS BOX: 2. A relay race was completed by 7 participants, and their race times are given below (in seconds).B = {10;10;8;7;5} Solution: Hunter A. Hunter B. Variance of hunter A equals s 2 (A) = 0,4 , variance of hunter B equals s 2 (B) = 3,6. Stands s 2 (A) < s 2 (B). Hunter A won the competition.
